IPhone – apply the iPhone 3GS backup to the iPhone 4S

backupconfigurationiphonerestore

As mentioned is a previous question, I made a backup of my old AT&T iPhone 3GS, then exchanged it for a new iPhone 4S at Sprint.

They transfered over my contacts. However, there's a lot of other stuff in that backup that I'd like to have on the phone. All my applications and their various configurations. For example, my GPS app has two years worth of saved locations.

On top of that, it looks like not all my contacts got transfered over for some reason.

So my question is, can I restore the AT&T 3GS backup onto my Sprint 4S phone without messing up it's Sprint-specific configuration? Will doing so cause the phone to think it's connected to AT&T?

Also, how exactly do you restore a backup onto an iPhone?

Best Answer

To restore from backup

  • connect the iPhone to your computer
  • wait for it to appear in iTunes
  • right-click on the iPhone listed under Devices and select "Restore from backup..."
  • select the backup you want to restore (there may be several)

Restoring will only touch user-specific content and configurations.
