Popo - I'm in a similar boat, post upgrade to ICS whenever I try and use my camera the phone locks up, says camera not responding, I tell it to close, phone reboots, gets stuck at small droid logo rom/bios screen. Tonight it took about 8 hard resets just to get phone working again. I am thinking I should have removed any third party camera apps prior to upgrade. Hopefully, update fixes, or it's a factory reset for me, then upgrade, good times. I really dug this phone until I was getting the update shoved down my throat.
