it's just a iphone with no phone, sms, or wireless data. if you want a touch you are really better off getting the iphone even if you don't have att. depending on the phone you get you can jailbreak it and use it on any carrier. hell if you have a jailbreak iphone and t-mobile you can call them up, tell you have a unlocked iphone and they have a data plan for it that you have to ask for.
