I downloaded and installed the update last night and now my camera app and music app won't work, when I select them it is followed by a black screen for like 4secs with like 3 or so vibration feedback vibraions then an error comes up, I've rebooted several times to no avail. Please help me out, I'm new to this crap lol also this is off topic but if samsung was so happening planning to release 2.2 legitly OTA, would I have to do anything to my phone like dp a factory reset or something? I just don't want to mess anything up!
