Here is my situation. I jailbroke my phone and am now trying to unlock it. I have an At&t iphone 3gs with modem firmware 05.16.05. I am looking for a way to unlock it. Also looking for a way to use the phone with out a data plan. I am around wifi enough to ue the features. I have googled and youtube the topic to death i just can't find a sure way to unlock or a sure way to not have a data plan. I am willing to pay for the unlock feature if i need to. Thankks in advance for your time.
