iPhone 3GS Does not Backup
The main issue is that the backup goes EXTREMELY slow. Too slow, considering it is an in-use phone that can't be left backing up for days on end. Now, last night I did try another backup, with the intent that I could leave it for well over a day. When I checked this morning, it looked as if the backup process had completed. But when I went to the Devices backup list in Preferences, it was listed as Unknown, backed up on 12/31/2000
Now, just a little troubleshooting info that I've tried:
-I've tried on a different PC running WinXP
-My main PC backs up my iPhone4 and my 1st-gen iPod Touch (OS 3.1.3) perfectly fine. So, I know there's not a PC issue preventing backing up.
-I've tried resetting Sync history and resetting warnings
-I disabled sending troubleshooting info to Apple (read one website that said that may cause a hang-up)
-I tried a powered USB Hub
-I switched to my brand-new never-used USB cable that came with the iPhone 4
-I removed ALL media and the largest apps from the iPhone, so as to make the backup as small as possible
-I have the exact same issues with a 1st-Gen iPhone, so I feel the problem isn't phone-specific.
Is there anything that I can do to get this data backed up? I desperately want to upgrade to iOS4, and I'm willing to do a factory reset to see if either will fix the problem, but I don't want to do either without a proper backup.
Thanks in advance for any help.
