So I bought the sim, with like $30 credit and Ive seen youtube videos showing people putting these SIMs into the iphone and everything is great, works fine. but for some reason when I put mine it, it says "no service" but under setting>phone it shows my number from the SIM. So how do I get it to work so I cant just receive and make calls on my prepaid pay as you go plan. Is there a way i can get around the thing ATT put out to block any non data plans on the iphone? Im not exactly an expert on all of this, i saw a file (.ipcc) that apparently did something but i wasnt sure howto install it. I have a 2g iPhone that was jailbroken through Blackrain, so if anybody can help me please do, itd be much appreciated. I tried searching all over the internet with no luck, so hopefully i can get here. Thanks!
