Ok Now. My problem is

1. The phone randomly restarts throughout the day until the battery dies. Usually it takes about 4 hours till its dead.

2. When in the media player and playing music if I click to go back to the music list it crashes. (Music continues to play after the crash and media is still controllable from the desktop screen. If I restart the phone it goes back to normal until I click back to the music list then its starts the problem all over again.

Anyone have any idea how to fix this or have a link to a more stable 4.2.2 rom for myTouch 4G?
