Even after the Symbian app died, Facebook maintained a Java MIDlet (M-261) for older phones.
Since the native app is non-functional, enthusiasts have discovered three workarounds.
For a long time, the most reliable "Facebook app" for the Nokia E90 was not an app at all—it was the Opera Mini browser.
Because the E90’s native WebKit browser was slow and struggled with JavaScript-heavy sites like Facebook, users turned to Opera Mini 4.x and 5.x. Here is why this was the de facto solution:
Current Verdict (2025): Even Opera Mini is a challenge. Modern Facebook’s TLS 1.2/1.3 handshake fails on most legacy browser builds, and the HTML structure of m.facebook.com is too bloated for a device with 128MB of RAM. You can maybe load the text-only version at mbasic.facebook.com, but it will be slow and prone to crashes.
This is the most reliable method for the Nokia E90 in 2025.
If you are a collector or retro-computing enthusiast, the hunt for a functioning Facebook app for Nokia E90 is a fascinating weekend project. The tactile QWERTY keyboard, the 4-inch landscape screen, and the satisfying hinge noise make it a joy to type on.
However, for practical daily use in 2025-2026: No.
The mid-2000s represented a fascinating crossroads in mobile technology. On one hand, you had the rise of social networking, with Facebook rapidly transforming from a college directory into a global phenomenon. On the other, you had the last gasps of the analog-era mobile phone design, perfected in devices like the Nokia E90 Communicator. Released in 2007, the same year as the first iPhone, the E90 was a masterpiece of a different philosophy: a clamshell phone that opened to reveal a full QWERTY keyboard and a high-resolution (for its time) 800x352 pixel internal display. The experience of using Facebook on this device—primarily through its dedicated Java-based application—was a unique, compromised, yet ultimately significant chapter in mobile internet history. It bridged the gap between desktop social networking and the always-connected smartphone era, highlighting both the ingenuity and the limitations of pre-iOS/Android mobile computing.
The most defining characteristic of the Facebook app on the Nokia E90 was its ability to leverage the device’s unique hardware. Unlike many phones of its day that relied on a number pad or a tiny touchscreen, the E90’s spacious, tactile keyboard made typing status updates, writing on friends’ Walls, and even sending private messages a surprisingly efficient task. The internal screen, when the device was opened like a mini-laptop, provided a landscape view that could display significantly more information than the postage-stamp-sized screens of competing phones. The Facebook app was optimized to use this space, showing a list of news feed items, a sidebar for navigation, and a chat window—mimicking the desktop layout in a rudimentary but functional way. For a business user or a power communicator, the E90 offered the closest thing to a desktop Facebook experience that could fit in a jacket pocket.
However, the app was severely constrained by the technological realities of its time. The Nokia E90 ran on Symbian OS 9.2 with S60 3rd Edition, and the Facebook app was a Java ME (Micro Edition) application. This meant it was not a native, integrated experience but rather a sandboxed program with limited access to the phone’s deeper functions. Notifications were not pushed in real-time; users had to manually refresh the app to see new likes, comments, or messages. The app’s interface, while usable, was slow and clunky by modern standards, with noticeable lag when scrolling through the news feed or loading photos. Furthermore, the lack of a capacitive touchscreen meant navigation was purely keypad-driven, relying on a series of directional clicks and soft keys—functional, but far from fluid.
Connectivity was another major hurdle. The E90 supported 3G (HSDPA) and Wi-Fi, which were advanced for 2007, but mobile data was expensive and networks were less reliable. The Facebook app was a data hog, and loading a single page of text and thumbnails could take 15-30 seconds. Uploading a photo taken with the E90’s 3.2-megapixel camera was a test of patience, often failing midway. Users lived in constant awareness of their data plan limits, a stark contrast to today’s unlimited, always-on expectations. The app lacked many features we now take for granted: no “Like” button (you had to write a comment saying “like”), no ability to tag people in posts or photos, no news feed filtering, and certainly no video playback. It was, in essence, a read-only portal with limited write capabilities.
Compared to its contemporaries, the E90’s Facebook app held a middle ground. It was far superior to the WAP (Wireless Application Protocol) or zero-rated “Facebook Zero” text-only interfaces found on basic feature phones. But it was inferior to the experience on a desktop PC or a laptop with a Wi-Fi connection. More critically, it was completely outclassed by the first-generation iPhone and early Android devices, which, despite their own early shortcomings, introduced capacitative touchscreens, kinetic scrolling, and a direct-manipulation interface that made social scrolling intuitive. The E90 represented the end of the keyboard-and-stylus era; Facebook’s future would be built for fingers, not buttons.
Ultimately, the Facebook app for the Nokia E90 Communicator serves as a powerful historical artifact. It represents a moment of transition—a time when a premium, productivity-focused phone tried to graft the emerging world of social networking onto an older paradigm of mobile computing. For its users, the app was a revelation: it allowed them to stay connected while on the go, participate in conversations, and check on friends from virtually anywhere with a signal. Yet, its slowness, lack of push notifications, and feature incompleteness were constant reminders of the gap between what was possible and what was desired. The E90 and its Facebook app were not a commercial failure, but they were evolutionary dead ends. They proved the immense demand for mobile social networking, paving the way for the integrated, seamless, and addictive experiences that would soon be perfected by the smartphones of the coming decade. The experience of pressing a physical key to refresh a loading bar on a 3-inch screen was, in hindsight, not a flaw, but the necessary prologue to the world of infinite scrolling we now inhabit.
Finding a working native Facebook app for the Nokia E90 Communicator is difficult today because the Symbian S60 3rd Edition platform is no longer supported by Meta. Here are the best ways to access Facebook on your E90: 1. The Mobile Web Browser (Best Option)
The most reliable way is to use the built-in "Web" browser or a third-party browser.
Facebook Touch/Mobile: Go to facebook.com. This provides a lightweight version of the site designed for older mobile devices.
Opera Mini: If the default Nokia browser fails to load modern security certificates, download Opera Mini (Java version). It often handles modern web encryption better than Symbian's native browser. 2. Facebook Java (J2ME) Apps
Since the E90 supports Java, you might be able to find archived versions of the official "Facebook for Every Phone" Java app.
Availability: These apps are no longer available on official stores. You would need to search reputable archive sites like Dailymobile or All About Symbian for a .jar file.
Functionality: Be aware that many of these apps may fail to log in because Facebook has updated its security protocols and APIs since the apps were last maintained. 3. Alternative Clients In its prime, the E90 used third-party social "hubs."
Gravity: This was the gold standard for social media on Symbian. While primarily for Twitter, it had Facebook integration. You can check if the developer, Janole, still offers a version that functions, though support is extremely limited.
fMobi: This was once a popular dedicated Symbian Facebook client. Like the official app, it relies on legacy APIs that may no longer be active.
Pro Tip: The Nokia E90’s full QWERTY keyboard and wide screen make the mobile web version (facebook.com) via Opera Mini the most usable experience for reading posts and messaging. Facebook Messenger Nokia - mchip.net
Running Facebook on a classic Nokia E90 Communicator today is a nostalgic journey back to the golden age of Symbian. While the original official apps have long since lost server support, the E90's massive 800x352 internal display still makes it one of the best vintage devices for browsing social media if you know the right workarounds. The Original Experience (Legacy)
In its prime, the Nokia E90 didn't have a pre-installed Facebook "app" in the modern sense. Instead, users relied on: Facebook for Every Phone:
A Java (J2ME) based application that provided basic news feed and messaging functionality. Nokia Social:
Later integrated into many Symbian devices, this allowed for status updates and photo sharing, though it was notoriously slow. Third-Party Powerhouses: Applications like
were the gold standard. fMobi offered a rich interface with chat, check-ins, and notifications, while Gravity transformed the E90 into a social media hub for Facebook and Twitter. How to Access Facebook on an E90 Today
Because modern security standards (TLS 1.2/1.3) have surpassed what the E90's original browser can handle, you'll need specific tools to get back online: 1. The Browser Method (Most Reliable)
The native "Web" browser on the E90 will likely fail to load Facebook due to expired certificates and modern encryption. Opera Mini: Opera Mini (version 7.1 or 8)
. It uses its own servers to compress and "re-render" pages, allowing you to access the mobile version of Facebook at m.facebook.com The TLS Patch: For advanced users, the TLS 1.3 patch
for Symbian S60v3. Once installed, it allows the native browser to open many modern websites again. 2. The "Facebook for Every Phone" Java App You can still find
files for the "Facebook for Every Phone" app on legacy archive sites. Installation Tip:
If you get a "Certificate Expired" error, try manually setting your phone's date back to 2010 or 2012
during the installation process, then change it back once finished. Why the E90 is still Special
For a vintage device like the Nokia E90 Communicator , getting Facebook to work in 2026 requires a bit of retro-engineering. Since the official Symbian Facebook app and the original Ovi Store are no longer active, you have to rely on third-party clients or optimized browsers to bypass modern security protocols (like TLS 1.3) that the E90's native browser cannot handle. Option 1: Third-Party Symbian Clients (fMobi or Borg)
These were the gold standard for Facebook on Symbian S60 3rd Edition. While they are no longer "officially" supported, community archives often host signed versions that still function with basic features.
: Known for its rich interface, it supports News Feed, Chat, and Notifications.
: Offers a lightweight, quirky interface that saves screen real estate on the E90's internal display. facebook app for nokia e90
: Primarily a Twitter client, it also has a decent Facebook integration that many users preferred for its speed. Option 2: Optimized Browsing (The Reliable Way)
The E90's built-in browser often struggles with modern HTML5 sites. Using Opera Mini
is the most reliable way to access Facebook today because it uses proxy servers to compress and "simplify" web pages before they reach your phone. m.opera.com on your E90 to download Opera Mini 7.1 Opera Mobile 12 : Open Opera Mini and go to m.facebook.com : If the standard mobile site is too heavy, try mbasic.facebook.com
, which is a stripped-down version designed for older data-light devices (though its availability can be intermittent). Option 3: J2ME Facebook App
There is a generic Java (J2ME) version of Facebook that was once pre-installed on many Nokia feature phones. You can often find the files on community forums.
The E90 supports Java MIDP-2.0, so these apps will run, though they may not utilize the full width of the internal screen. Access Facebook faster with Opera Mini
Nokia E90 Communicator is a classic device from 2007, and because it runs on the Symbian OS (S60 3rd Edition), there is no longer a dedicated "Facebook app" that functions in the modern sense. Most legacy Symbian apps lost support as Facebook updated its security protocols and APIs years ago.
If you are looking to access Facebook on this specific piece of hardware today, your options are limited to the following: 1. The Mobile Browser (Best Option)
The most reliable way to access Facebook on an E90 is through its built-in browser or a third-party one like Opera Mini.
Facebook Mobile (M-Basic): Navigate to facebook.com. This is a lightweight, text-heavy version of the site designed for older mobile browsers and low-bandwidth connections.
Opera Mini: If the native Nokia browser fails to load modern security certificates, downloading Opera Mini for Symbian often provides a better "bridged" browsing experience that can handle newer web standards. 2. Community-Driven Legacy Archives
While official support is gone, retro-tech communities sometimes preserve old .sis (Symbian installation) files.
Sites like All About Symbian or the SIAM (Symbian Archive) often host archives of old apps.
Warning: Even if you find an old Facebook .sis file, it will likely fail to log in because the servers it tries to connect to no longer exist or don't recognize the old authentication methods. 3. Third-Party Social Clients
In its prime, the E90 could run multi-protocol IM clients like Nimbuzz, Fring, or ebuddy, which integrated Facebook chat. Most of these services have also shut down or removed Facebook integration, but they were once the "piece" of software users relied on.
Technical Note: The Nokia E90 was announced in February 2007, making it nearly two decades old. Modern web security (SSL/TLS) is the biggest hurdle for this device; many sites will simply refuse to load because the E90's certificates are expired.
This is a reference to a historical deep feature from the late 2000s — specifically, a native, optimized Facebook client for the Nokia E90 Communicator, which ran Symbian OS (S60 3rd Edition).
Unlike standard Java ME apps or mobile web shortcuts, the Facebook app for the E90 leveraged the device’s unique hardware and OS in ways most phones couldn't:
Full keyboard shortcuts
Because the E90 had a hardware QWERTY keyboard, the Facebook app supported keys like:
Background push notifications
Using Symbian’s background process capability, the app could receive notifications even when closed — years before Android/iOS did this reliably. It used persistent TCP connections, not SMS or polling.
Integrated contact sync
The app could sync Facebook profile pictures and birthdays directly into the E90’s native Contacts app (not just inside Facebook), with two-way linking.
Offline drafts & queue
If you lost 3G/EDGE signal, you could write status updates, comments, or messages offline. The app stored them in a queue and sent them automatically when reconnected — a feature even modern mobile apps sometimes lack.
Data compression
Nokia and Facebook collaborated to route traffic through Nokia’s proxy servers, compressing images and HTML to reduce data usage, which was vital given expensive 2008–2010 data plans.
Keep your Nokia E90 as a digital detox device or a dedicated email/WhatsApp machine (via the old WhatsApp Gateway – which also requires a hack). For Facebook, use a modern smartphone. But if you must browse your feed from a 2007 icon of engineering, fire up Opera Mini and point it to mbasic.facebook.com.
Remember: The spirit of the Facebook app for Nokia E90 lives on in the memories of status updates typed on a physical keyboard and photos uploaded via EDGE. The app is gone. The communiqué remains legendary.

While there is no longer an official Facebook app for the Nokia E90 that works with modern security standards, enthusiasts can still access the platform using legacy workarounds. The Nokia E90 Communicator, a legendary Symbian S60 3rd Edition device, was released long before the era of modern mobile apps, but its expansive internal screen and full QWERTY keyboard still make it a unique tool for text-based browsing. The State of Facebook on Symbian in 2026
Official support for Symbian apps ended years ago, and most legacy Facebook clients like Nokia Social or fMobi no longer function because they cannot connect to Facebook's updated API. Modern security protocols (TLS 1.2/1.3) also prevent the E90's stock "Web" browser from loading most encrypted sites, including Facebook. Best Methods to Access Facebook on Nokia E90
To get Facebook running on your E90 today, you must use specialized browsers or third-party Java-based clients that handle modern encryption.
Opera Mini (Recommended): This remains the most reliable method. Opera's servers act as a proxy, rendering the modern Facebook site into a lightweight format the E90 can handle. You can navigate to m.facebook.com to access a simplified version of your feed.
Facebook Java App (J2ME): Older "Signed" versions of the Facebook Java app (like version 3.4.1) sometimes still work if you can find the .jar or .jad files on archive sites like BoostApps. These were designed for basic phones and are highly efficient on the E90's hardware.
Gravity: Once the gold standard for social media on Symbian, Gravity was a premium client that supported Facebook and Twitter. While its Facebook functionality is largely broken due to API changes, some users in the Symbian community continue to develop "patches" to keep these legacy apps alive. Installation Tips for the Nokia E90
Date & Time: Ensure your phone's date and time are accurate. If they are off, security certificates will fail, and no app will connect to the internet.
S60 Hacking: To install many of these "abandonware" apps, you may need to "hack" your Symbian OS to bypass certificate errors. Tools like Norton Hack or HelloOX are commonly used by the community for this purpose.
Memory Management: The E90 has limited RAM (128 MB). To avoid crashes while browsing Facebook, close all background apps and use the internal widescreen for a better "desktop-like" experience.
For the most current community-made fixes and apps, the r/Symbian subreddit is an active hub for E90 users in 2026.
While there is no modern "Facebook app" currently supported for the
, you can still access the platform using legacy methods. Since the E90 runs on Symbian OS S60 3rd Edition (v9.2), the original official apps have long been discontinued. 1. Modern Web Access (Native Browser Patch)
The most effective way to use Facebook on a Nokia E90 today is through the native web browser after applying a security patch.
The TLS 1.3 Patch: Most modern websites, including Facebook, require TLS 1.3 security protocols which the E90 does not support out of the box.
How to apply: Enthusiasts on forums like Reddit's Symbian community suggest installing a TLS 1.3 patch from legacy archives (such as nnp.nnchan.ru/tls).
Mobile Site: Once patched, you can navigate to m.facebook.com or the ultra-lightweight mbasic.facebook.com. The E90’s large internal 800x352 screen is particularly good for these mobile views. 2. "Facebook for Every Phone" (Java App)
Historically, Nokia devices used a Java-based app called Facebook for Every Phone.
Compatibility: This was a .jar (Java) application designed to work on over 2,500 different handsets, including Symbian devices like the E90.
Current State: While you can still find .jar files for this app in online archives, many users report login errors because Facebook's servers no longer properly handshake with these older Java clients. 3. Alternative Browsers
If the native browser remains difficult to use, third-party browsers often handle older web standards better:
Opera Mini: This remains the gold standard for legacy phones. It uses proxy servers to compress and re-render modern websites (like Facebook) into a format the E90 can handle.
UC Browser: Another popular alternative for S60v3 that sometimes offers better stability for social media sites than the stock Nokia browser. Summary of E90 Capabilities Facebook for Everyone (Facebook Feature Phone App)

Title: Revisiting the Brick: Getting a Facebook App to Work on the Nokia E90 Communicator in 2024
Date: [Current Date] Author: RetroMobile Junkie
There are phones that are smart, and then there are phones that make you feel like you’re launching a nuclear missile every time you open a text message. The Nokia E90 Communicator falls into the latter category. With its clamshell design, full QWERTY keyboard, and that gloriously wide internal 800x352 pixel screen, it was the pinnacle of business communication in 2007.
But 2024 is a wasteland for Symbian OS. So, can you still run the Facebook app on an E90? Short answer: Not really, but here is the better way.
The Official App is Dead (Long Dead)
Let’s get the bad news out of the way. The official Symbian Facebook app stopped working around 2015-2016. If you try to install the old .sis file today, you’ll get a "Certificate Expired" error. If you bypass that (by setting your clock back to 2010), you’ll get a "Connection Error." Facebook’s API protocols have evolved so much that the E90 simply speaks a different language now.
The "Fake It" Methods That Actually Work
If you want to check your News Feed on that beautiful 4-inch internal display, you have three options:
1. Opera Mini (The Gold Standard) Forget the native app. Opera Mini is the savior of every vintage smartphone. Download the Java (.jar) version. Opera Mini routes traffic through Opera’s servers and compresses the hell out of it.
2. The "Snaptu" Ghost
Old-school users remember Snaptu—a Java app that acted as a proxy for Facebook, Twitter, and Flickr. Snaptu was bought by Facebook and killed, but the old .jar file floats around forums.
3. The Web Browser (Not Recommended) The built-in S60 browser is a museum piece. It doesn't support modern TLS certificates, meaning Facebook will scream "Web: Page cannot be loaded" before you even type your password. Don't waste your time. Current Verdict (2025): Even Opera Mini is a challenge
The Hard Truth: Accounts & 2FA Even if you get mbasic.facebook.com running in Opera Mini, you’ll hit a wall: Two-Factor Authentication (2FA). The E90 cannot render the modern 2FA pop-up windows.
The Verdict: Why Bother?
Let’s be real. You aren't going to watch Reels or comment on memes with this phone. The E90’s CPU (332 MHz OMAP 2420) screams in agony just loading the notification bell.
However, if you want a distraction-free Facebook—just text statuses from close friends, no ads, no video autoplay, just pure "What’s on your mind?"—the Nokia E90 with Opera Mini is a zen experience.
It turns Facebook from an addiction into a utility. You open it, check your messages, close the lid, and get back to work. That is exactly what this communicator was designed for.
Final Setup Checklist:
Does anyone else still carry a Communicator as a secondary device? Let me know in the comments—if you can get the keyboard to type that far.

, you can still access the platform using legacy methods designed for the Symbian S60 3rd Edition operating system. Primary Access Methods
The most reliable way to use Facebook on a vintage device like the E90 is through a web browser rather than a dedicated application: Mobile Browser (m.facebook.com): m.facebook.com
into your E90's native browser or Opera Mini. This loads a lightweight, text-based version of the site compatible with older hardware. Opera Mini: Opera Mini
is often more effective than the built-in browser because it uses server-side compression, which helps bypass modern security (TLS) requirements that the E90's original browser may struggle with. Legacy and Third-Party Apps
Historically, several applications provided a more "native" feel, though their functionality today is limited by expired security certificates and API changes: Get to the Facebook mobile site (m.facebook.com)
