I was thinking of doing this for a long time but was not getting that strength to play with my 20k+ stuff .... but finally yesterday i turned my N73 into N73 ME... well there were some differences and the main difference was the GREEN THEME which comes inbuild with ME and also the music player which is more enhansed in ME series... The over all sould quality and player software has increased a lot and it is working great now... So the main changes were: 1. Idle Screen with new clock. 2. New Main Menu Music Icon. 3. New Default Themes. 4. New Music Player with Album Art. 5. Music Player audio settings (Stereo widening is super cool!!!) 6. Music Player Visualization - Oscilloscope 7. Music Player Visualization - Spectrum 8. Firmware Version: 3.06220.127.116.11 Procedure Well i used 2 softwares for this 1. Nemesis Multi Flasher (to change the pid) and Nokia Phone updater (to install the firmware) Before you decide to update your Nokia N73 to the Music Edition, know that this may void your warranty and you run the risk of breaking your phone.
