Very useful. I'm currently on £15.50 O2 simplicity with no contract, and i'm weighing up paying Apple £600 directly for the unlocked phone on entering a new contract with O2. Looks like the cost of £600 up front and my current £15.50 a month is about the same total over 2 years at the £26 a month option for the 32gb phone... Only difference is the contract gives me way more voice minutes...
