Hi, So Ive managed to secure an iphone 3g of the bay. First things are, do i need to check for anything in particular when going for the cash on collection? Secondly, what is going on with the whole unlock thing nowaday? Can I unlock the iphone 3g to any network in the uk? I have an o2 contract at the moment that has 5 months left on it. Thanks you so much in advance for help and advice given Much appreciated.
