Also, is there a way to get silent and vibrate modes back?
Doesn't look like the question has been answered yet. I'm having a similar problem. I have a vibrate mode, but not a silent mode. In 2.1 when you press the volume button down, it lowers the ringer eventually to vibrate, and then silent... However, now with 2.2, it stops at vibrate and doesn't go any further to "silent".
Any help on this matter would be a huge help.
Thanks,
Josh
You can still swipe to the left on the unlock screen to put the phone on Silent, or hold down the power button and select Silent Mode.
