Hello guys, I really need an assistance on this one. I apologize if the question seems ridiculous, but I have searched the forum before asking this question. My friend gave me an iPhone 4 already upgraded to IOS 5 on AT&T networked - locked. Now I want to use this phone in Germany, for that, presumable I need to unlock and jailbreak it. Someone suggested to me to get this Gevey Pro card as an easy alternative, which I did. The problem is that I cannot get passed the sim card activation screen, because it tells me that the sim card is invalid. Can someone tell me, where should I begin or is it at all possible to use this phone in Germany? I am not getting how can I get passed this activation screen if I don't have original AT&T card and all other cards even with Gevey Pro are not recognized on the phone without some kind of jailbreaking/unlocking. Thank you for a competent answers. All appreciated. G.
