believe it or not the 8gb iphones have sold out everywhere!!! i was going to purchase one and unlock it but was told by both CPW and O2 that they are sold out and if any further stock comes in will be sold for origional price(apparently this was in small print when 8gb was reduced!!!)
Also apple's annual conference is on June 9th and are expected to announce the bigger and better iphone with 3G and better camera!!! My advise would to hang on in there, it might be £269 again but the features would be well wrth it!!!
