I tried to manually install 2.2 a couple of days ago and I got a message saying that it failed. I decided to just hit reboot and deal with 2.1 for a little while longer. When it rebooted I was at 2.2 and everything seemed to work fine. However, yesterday my phone would not unlock after hitting the unlock button so I did a battery pull and its working fine again. I have a feeling it might not have installed right? Should I go back to 2.1 stock and wait for the 2.2 update or will the "failed" manual update not be a problem?
