Hi, I'm using a jailbroken iPhone 3G on iOS 4 and my baseband is 05.13.04. First of all, I jailbroke it using redsn0w and then after letting Cydia reorganize itself, I installed ultrasn0w 0.93 and I should be unlocked and all good right? Now, I'm on Rogers in Canada and whenever I pop in the Fido sim card, the iPhone locks itself up and displays the notice "different sim connected please connect to itunes". I've done it to no avail and popping back my Rogers sim card and the phone works fine. So what do I do to get it working? Much appreciated.
