Youtube Jar 240x320 «100% AUTHENTIC»
In the world of mobile phones before iOS and Android, Java ME (Micro Edition) was the standard platform. Applications were packaged in JAR (Java Archive) files.

The old .jar files relied on Real Time Streaming Protocol (RTSP), which YouTube has largely disabled. In the world of mobile phones before iOS
