I have a iPhone 4 and it was with AT+T. The OS is 5.1.1. I used absinthe 2.0 to jailbreak it so I could go with T-moble. It jailbroke ok but when I received the t-moble sim card-no service. I have tryed with both sims to rejailbreak the phone but I get Phone is not activated with absinthe. I also get in iTunes (sim card in this phone does not appear to be supported ) so I cant restore or do anything in iTunes. How can I start over or do anything from here?
