I cracked my IPhone 3g screen, and rather than pay for a replacment, I'm going to reactivate my old 2G IPhone to use for awhile. I backed up the 3G IPhone in Itunes. I got a new sim card from AT&T and activated the 2G IPhone, but the contacts aren't migrating from the phone I have been using. The two phones have the same name in ITunes since I had used the 2G phone previously. Any suggestions on how to get ITunes to bring my updated Contacts over to the 2G phone? Thanks.
