tried unlocking and jailbreaking my iphone 2g with blackra1n and bootnueter. now when i enter my sim card i get service it says t-mobile on the top i can receive calls and texts, but i cannot make any. It says wrong sim and i can only make emergency phone calls. i tried to restore it and do it again but when i do that it just says error and it is unable to do so. i do have 3.1.2 software. does anyone have any idea on whats going on?
