Restore unlocked iPhone before warranty repair
I've searched everywhere about what to do before I bring my unlocked first generation iPhone to Apple for repair. All I've come up with is forum posts suggesting a DFU mode restore of my phone. This is what I did, the problem is that the phone is still unlocked.
I know this because although the iPhone is now showing the activation screen, it is connected to the ATT network when I put my Swedish SIM card in it. If it was truly virginized it wouldnt be able to get a reception with this SIM card.
The phone is a 1.1.1 OTB so I assume it still has the 3.9 bootloader. During the last DFU mode restore it was updated to 2.0.2.
Help is much appreciated!
