I got my iphone unlocked and jailbroken. I'm still running OS 3.0 and everythings been working great. SMS, MMS, Email and internet. I've never done an upgrade while jailbroken/unlocked so I'm not sure what to do and the guides are really details to understand what to do.. Do I lose all my data like sms/mms? I understand I have to start from a restore and then jailbreak and then unlock. but that's it.. and also, when is the unlock for 3.1.2 projected to be out?
