Since the 2.1 update my phone had been super slow, locking up, etc. I did the hard reset after backing things up and it seems to be better now. However, there are so many other programs that automatically run now like Amazon MP3, Bluetooth Sharing, Music & some others. These weren't running before the update and my battery life is much less than it used to be. Is there a need for these to be there and can you permanently remove them or other "system" programs? Thanks!
