The upgrade to iOS 4.2 failed, and is unlikely to work again on my Windows XP platform due to technical issues.

What I would like to do is transfer the itunes backup files to another computer which has Vista on it, so I can try the procedure again.

Which files do I need to copy across, so that once I plug my iPhone in, it will restore and update correctly (which kept failing on the other platform)

I would appreciate your solutions to help unbrick it!

Thank you!

    On Windows XP, backups are stored in +\Documents and Settings\(username)\Application Data\Apple Computer\MobileSync\Backup\+ but in Vista, backups are stored in +\Users\(username)\AppData\Roaming\Apple Computer\MobileSync\Backup\+. I would assume if you copied and pasted the Backup folder from the XP drive onto the Vista drive, you would be able to restore from it.

    If you don't see the +Application Data+ folder or the AppData folder, use these articles to view them:

    You don't need to transfer your iPhone's backup to another computer. iTunes should create a backup for your iPhone as the first step before imstalling a firmware update but to be sure, you can manually create a backup for your iPhone before installing the update which will be current. Right click on your iPhone under Devices in the iTunes source list and at the menu window that appears, select backup.

    No iTunes content on your iPhone is included with your iPhone's backup and the same for any photos on your iPhone that were transferred from your computer.

    To transfer your iTunes library from one computer to another, follow the steps included with this link. You will also need to authorize the other computer with your iTunes account with iTunes.
