I recently bought a iphone 3GS version 3.1.2 off ebay and it is locked to telstra and I am with optus I have tried to jailbreak it with blacksnow but it still says "no service". Any help would be much appreciated! Cheers, Jacinta
I do believe you have to have optus unlock it for you since you have a factory unlocked telstra phone. If you take the phone to optus I'm pretty sure they will unlock it for you for free.
