I will at some point, well I wont be paying anything for it that's for sure.
I will wait until I got back to the UK at Christmas and as I still have my UK contract pretty much every phone is free when I get to upgrade every couple of years. Probably not 5 even though it wouldn't cost much but 4 would be free.
I would never pay the ridiculous prices here for a phone when I can get one for free at home, bring it back, get it unlocked, job done.
