I just recently bought a used iphone 3G that was used previously on the AT&T network. My plan is to use it on Walmart's "straight talk" plan. My question is, do I have to unlock this phone, since straight talk uses AT&T towers for their iphone plans? I think that I just need to get the straight talk sim card. Please correct me if I'm wrong.
