Hi guys, I know another thread with somebody who has problems, but I can't find an answer to my problem somewhere. I tried to jailbreak my iPhone this morning. It all worked fine. I have cydia on my iphone 3GS on modem firmware 05.13.04 and iOS 4. While the jailbreak i had a Vodafone sim card in it but it still says no service. I also tried it with two other sim cards... Always the same mistake. Does anybody know how to fix that?
