Hi, I have been having problems for the past 3-4 months with syncing and backing up my iPhone 3GS. I'm running Windows 7 Pro with no 3rd party software installed. My computer often has a hard time recognizing that my iPhone has been synced/backed up before, and often times it will think I am connecting a brand new phone for the first time. I can usually get around this issue by disconnecting my iPhone and plugging it again. Once the iPhone is recognized, it will sometimes sync, and other times fail at syncing. When I'm lucky, it will decide to sync, but then it will fail at creating a backup, or restoring from a backup. The error codes/messages I get are usually something like "backup session failed" or "internal device error". I feel as though ever since I got this phone 3-4 months ago I have been doing nothing but working around the issues at heart. I'm at my wits end... any suggestions are much appreciated.
