I recently brought a "Sim Free" 3GS on e-Bay. When I received it, I noticed that it had Cydia installed, and was jailbroken. Is it possible to find out if the phone is actually unlocked, or if it was unlocked when it was jailbroken. I want to upgrade to 4.3.1 iOS, but I don't want to lose the unlock if thats the case. If its any help, its baseband is 06.15.00.
Thanks in advance guys
