hey bros, i have an iphone given from my brother from UK. He uses the UK network 02 for this iphone. Thus, this phone is locked to the 02 network, a network in the United Kingdom. Currently, its baseband is 5.09 and im wodering can it be unlock. However, it is jailbroken but cannot be unlocked due to an upgrade to 3.1.3 firmware. Can it be unlock for malaysian line? Any suggestions fellow LYNers?

btw, i heard that by using da blacksnow from cydia to unlock, it can be done. is it real?
