    Upgrade the latest OS via itunes and yes you can unlock it yourself. Google for tutorials, or even youtube.

    Can be done online at O2 with the online help assistant
    Only takes a few minutes.

    Its a phone i brought of e bay so i dont have a contract or pay as you go account registered to the phone, to unlock using the guidance on the 02 website.

    Get a O2 pay and go sim instore.
    Top up £20
    Make a few calls so O2 know it's being used
    Apply for the unlock online.
    Done

    I'm betting this is on current firmware so can't be unlocked via jailbreak

    I'd check it with an O2 sim from someone first to make sure it's not been blacklisted. A LOT of iPhones sold on ebay are. There's no point bothering with the rest if it is. . .

    Is it a 3g or a 3gs? 3g can only be updated so far and is also much easier to keep unlocked unofficially.
