Ok so i bought an iphone 3gs. When its on, it says connect to itunes when u do it says please insert sim card.So i did, now it says please use official sim card or supported.Now my question is, if i get an official one will i need to activate the phone? I just want to unlock the phone but i cant without sim card, is there an alternative way?Can i unlock the phone without a sim card? How would i find out the os to jailbreak it then unlock.I know how to unlock just never been in this situation.
