I've had 2.2 for, what?, two days now and everything was going smooth. The only thing I noticed is that the camcorder still will not take close-ups using the volume buttons like it was supposed to with 2.2. But today, several things that never went into landscape mode went into landscape mode, but not in the usual way, but in reverse. By that, I mean that usually you would go into landscape mode by moving the top of the phone down to the left. However, this landscape mode appeared as though I moved the top of the phone to the right. Also, when I pull the phone out of its holster, and touch the volume buttons, I go into the car dock apps. Looked all over the system to see if the volume control buttons had other functions beside volume control and putting the camera (only the camera) into a close-up. Couldn't find anything. Neither of these happenings are terrible, just annoying.
