s60tube works on java phones in 2025 which had youtube in its young days

it works by searching a video, entering the "2yxa.mobi" section, you will see "rstp mp4, 3gp, low, high bitrate" and make sure its the "rstp" varient. once you click any of these options, you will enter into a converter, click refresh until its completed and says "the file is ready". click on the "RTSPI" option, once it reloads, click on it again and it will trigger the streaming app.

tested on nokia asha 501.
