Hi, my brother currently has an iPhone 3GS and is going to upgrade to the iPhone 4. He said he would let me have his current 3GS if I wanted it. However, I don't want the data plan. I currently have an HTC Fuze, another AT&T smartphone, but do not have a data plan, and voice only. I was wondering if I unlocked the 3GS and put in fake APNs, would I have to add a data plan? Thank you
