Default Unlocking!

ive read that there are many threads on unlocking the gt-s5570 but cant find any!!! i cant be looking in the right places but then again i have been dumb enough today to take my galaxy note2 in the swimming baths this morning.
can somebody kindly point me to a unlocking guide for the gt-s5570, its running android 2.3.6, ive just rooted it and running stock rom on o2uk if any of that makes any difference to the guide lol
