I was using my mail app today and everything was fine. Then when i went to check it it told me it could not retrieve mail "imap.gmail.com error password or user name incorrect" It let me log in on my computer but not my ipod touch. I did not change anything and even deleted the account on ipot and added it again ensuring everything was correct. I decided to change my password on my computer and when i re added it to my ipot with the new password it worked. Any clue why this happened?
