My 3G iPhone wants to delete 13 contacts when I sync. I know that I haven't deleted that many and I haven't deleted them from my address book. Is there any way to back up this data before a sync? Is there any way to determine which contacts it wants to delete? iPhone: Firmware 2.2 (Jailbroken) Software: iTunes 8.1 OS: Windows Vista 64bit Syncing to: Windows Address Book Also, are there any benefits to syncing to a Google Contacts list instead?
