I have a new iphone, just brought it home from AT&T. I have not plugged it into the computer yet or done anything with it at all.
What is the best way to unlock it? I had a 3GS with 3.1.2 that I unlocked with Blackra1n and it was buggy as hell. I hated it so I thought I'd try an upgrade.
Can anyone please advise me so I don't screw it up.
Here's all the phone info:
Version: 4.2.1 (8C148)
Modem Firmware: 03.10.01
