Hi, I just bought a (supposedly) factory unlocked iphone from ebay. However, when I switched it on, I can see an app called blackra1n on the 2nd page. Does this mean that it is actually just jailbroken? As I understand - blackra1n is used to jailbreak iphones but not to unlock them, so is it possible that the phone is factory unlocked and jailbroken with blackra1n at the same time? Is there any way I can check if its actually factory unlocked? There aren't any other apps like Cydia on there, just blackra1n. Thanks!
