Q: iTunes could not backup iPhone because the iPhone disconnected
I've tried seaching for an answer for this problem and can't find one that works. I've tried the basics and even restored my iPhone 4S (and restarted it). Yet, I still keep getting the above message every time I try to back up even though my iPhone is hardwired to my laptop. Any other ideas out there to solve this one?
Thanks!
iPhone 4S

the next thing I would check is the cable and connector. However, you said you had restored the phone without error, so that is not likely to be the problem.
It's possible that your backup is corrupted, although that usually causes the backup to hang rather than quit. You can try deleting the backup (iTunes Preferences, Devices section); this will clear the problem if the backup is corrupt. If you don't have a backup of it and don't use Time Machine you may want to just rename the backup folder instead of deleting it. It is located at ~/Library/Application Support/MobileSync/Backup/. Rename the folder at the end to Backup.sav or something similar.
