    Well, I have been looking around these days for solution to upgrade my iphone to3.1.2, I feel this is the right forum to ask. I have to admit when it comes to Jailbreaking and unlocking Iphone, I no ideas at all.
    Descrip:
    Iphone 3g, 16Gb
    Version 2.1(5F136)
    Modem Firmware 02.11.07
    Whether it was jailedbreak before, i have no idea since my bro gave it to me. I notice my iphone has a small plastic chip underneath the sim card. And notice some other iphone doesn't come with that. I presume my iphone is not yet unlocked, right?
    Then I am concerned about my contact. How do i back-up before jailbreak and unlock, any program or using itune? Because those contacts are valuable to me.
    I'm living outside of US.

    Thank you very much.

    If you have all your contacts sync to a desktop utility like Outlook you will be able to sync them back to the phone when you set up as new. If not, take a look at this lync and get to knoe Chronus.

    Well, it seems i got passed the jailbreak and unlock successfully. One thing remain though, I can't sync games and applications to my iphone. I remember that iphone need at least one genuine application in the machine in order for it to sync, is this true?
