Just been over to the guys at Iphone Dev Wiki and followed there free solution and then popped in my 02 sim and my Apple iPhone works just fine. 🙂
I think they are also working on a easier 1 click version soon, so for those that dont fancy doing all the steps, I dare say in a few days, there will be a easier way.
Rememeber to drop a donation to the hard work these people put in also!
Enjoy your iPhones 🙂
