  • To use an AT&T iPhone 4S with straight talk, does it need to be unlocked? I'm going to switch my iPhone 4S over from AT&T to straight talk. I'm unsure wether the phone needs to be unlocked or not. Some blogs say it doesn't, some suggest it. I've had mixed answers from straight talk reps. I don't know what to think! Does it need to be unlocked or not to use the phone with straight talk?
  • Still possible to use att iPhone 3GS on straight talk? I have an AT&T iPhone 3GS with no SIM card.

My question is basically how do I get a SIM card for my phone that will allow me to use AT&T towers? Please be as specific as possible a link / how-to won't hurt my feelings!
