Hi, Just recently moved from UK to US and trying to get my new AT&T SIM card activated on my O2 iPhone. I've run through the jailbreak & unlock steps using firmware 2.2 and QuickPWN, and the process works fine. Wiped all my data, but I was expecting that... Problem is, when I put in the other SIM card from AT&T (they gave me a brand new one for once I had unlocked the iPhone) and then reconnect to iTunes to activate it, iTunes tells me the SIM is unsupported, which makes it sound like the unlock failed. But when I re-run the QuickPWN, it tells me that the settings (including the unlocking bit) are already done. Any ideas or suggestions? Thanks!
