Is there a way to change iPhone backup location? I don't have enough disk space on my PC to store whatever is backed up by iPhone. Is there a way to change location to where iPhone backs up the data? I want to back it up to my external hard drive.
It looks like you can if using Windows.

Is OS X the backups seems to be stored in the following location ...

~/Library/Application Support/MobileSync/Backup


... but I don't think you can change that location.
