Hi, I have a iPhone 3G which was Jailbroken (redsn0w) and Unlocked (ultrasn0w). I can't make Push Notification to work on this phone - although I made it work on my other 3GS (also jailbroken/unlocked) I think that's because the 3GS WAS activated with ATT and I don't know if the 3G was (as I purchased it from a friend of mine).... So, how can I force the 3G to be (re)activated with ATT ? ps: I do have a sim card that was used to activate another 3G iPhone... Please anyone help me ?
