So last night i updated my iPhone from 2.0.2 to 2.1 and after i updated eveyrthing went fine. After u restored from a back the iphone stays at the apple logo vibrating and wont stop. I also noticed when i was backing up BEFORE i updated that the backup took about 10-15 minutes so i think that the backup is corrupted so when i went to restore from a backup it messed up my phone but i am not sure. Can anyone please help becuase i have done this about 4 times and same results eveytime.
