Solution for -1303 error when upgrading to iOS 5
Hello all,
I just wanted to share a potential solution to the -1303 error some people are getting when they try and install iOS 5 on their iPhone (in my case, it was an iPhone 4). The full error message is:
"An error occurred while backing up this iPhone (-1303). Would you like to continue to update this phone?
Continuing will result the loss of all contents on this phone."
For me, this error occurred because I had a junction point set up in Windows 7. This was used to store backups on another drive (as my OS drive is small). To resolve this, I copied the backups to another location and deleted the Backup folder/junction point in C:\Users\[User]\AppData\Roaming\Apple Computer\MobileSync.
I then started the update process again, as per normal, and it worked!
iPhone 4, Windows 7
