    Hi guys

    I have an S2 which I would like to Unlock on all networks. At the moment it only runs on Three (3g) UK network and is on Gingerbread.

    What Would be the simplest way to unlock it? Also to upgrade to Jellybean.

    No. Otherwise I would have told you to. There is no need to root your phone for THREE to unlock it and you do not need to be rooted to flash a stock Samsung firmware as I mentioned.

    You asked for, "the simplest method to unlock the phone". One call to THREE is that method!
