I was wondering whether you have to take out the SIM card when selling Sprint IPhones. I know that with ATT you have to because it connected to the account, but I don't know if that applies to Sprint as well because they use different tech. Does anyone have any idea? I debating on selling my phone and I don't know if I would have to take out the sim or I can sell it with the SIM in it as long as I activate my account on a different phone. Thanks for any help you guys!
