Hello. I recently received the iPhone 3gs ios phone to the newest software update 5.1. My parents are to cheep to pay the monthly internet/ data plan, so they told me that I needed to somehow unlock the phone where at & t could not recognize and charge me the extra internet fee. So I need to know how. Is there tutorials or websites that someone can recommend that are the easiest and quickest way to do this to my phone.

\Ps. I would like to Jailbreak it too.
