I bought a second hand Iphone 3gs which is working fine on other carrier (not AT&T) . So I know its not locked, it also came with Cydia installed so I know its jailbroken. But in Cydia I don't see any of the unlock Packages or Sources that are supposed to be used to unlock the iphone. Does that mean its officially unlocked? Right now its on 3.1 (7C144) and modem firmware 05.11.07. Anyway to figure this out? Thanks in advance.
