The "10.3.3" you are looking for generally refers to the final build released publicly. The specific software release version you should look for is 10.3.3.3216.
Why 10.3.3? This was the last major update for the BlackBerry 10 OS. It improved Android app runtime (though it is now obsolete due to Android APK changes), improved camera performance, and patched the "Year 2038" date bug that caused older devices to stop working if the date was set too far forward.
Some forums mention a "leaked" version 10.3.3.2046. Do not use it. The official final release is 10.3.3.3216 (software release 10.3.3.2205). The leaked version has a critical bug where the hub crashes after a week of use. Blackberry Z10 Stl100-2 Autoloader 10.3.3 Download

After installation, go to Settings > About > OS Version. You should see 10.3.3.3216. The radio version should be 10.3.3.3217.
