Hi, Both my wife and myself have bought 2nd hand iphones 3Gs. We dont want to be tied to a network so were hoping to jailbreak them. Although the firmware on these are 3.1.3. The behaviour of them is different though when we turn them on. When I turn my iphone on I cant do anyhing but make emergency calls. Although my wifes iphone I can see and use the applications. Can someone please explain why they are different? Is my wifes iphone already unlocked?
