I bought a used iPhone 2G and received it in the mail yesterday. I am trying to update the iPhone in iTunes to 2.2.1. It seems to have updated to 2.1.1 (I may have done this update myself but I'm not positive). However, it doesn't want to go to 2.2.1 and I have no idea why. I click "Check for Updates" in iTunes and it says that my version 2.1.1 is the current version which I don't think that it is. Any ideas on how I fix this?
