Hello everyone, i am very new to this iphone world and i just purchase a sprint iphone 4s on ebay and the phone have clean ens and everything, so my question is can i activate the phone without having sprint as my carier? I have T mobile atm, i was thinking about unlock it with gevey ultra so i can use it on my t mobile network but the phone came with ios 6.0
noway to jailbreak for cydia and no cydia = no furious mod, no furious mod = gevey wont work 


so my point is can i still activate this phone without sprint account and wait for a way to jailbreak and use gevey sim later on in the future? thanks alot everyone... I really appreciate your help.
