Im thinking of getting a iPhone on PAYG from the CPW or something as I dont really use the phone alot (calling and texting wise) to warrent a £30/35 a month contract. Ill probbally use it more data wise and the 12 months free data seems cool Does this include emails and GPS use? or is it just web use?

Also anyone with a PAYG iPhone, were there any problems in getting it setup?
