So finally the O2 page is open to allow existing customers which are not at the end of thier contract to switch to an iphone tariff, all you need to do is get a 2nd hand iPhone (ebay) either v1 or 3G. (I have been told by O2 that if you get one locked you will need to activate it through iTunes as an existing customer, they said that you will need an iPhone orig sold by O2. Now I cannot check this but the form to ask to change to an iPhone tariff asks for no details about the iPhone you have bought so you can swap to an iPhone tariff and then just buy and use an unlocked iPhone! WOOT! page to transfer your tariff to an iPhone tarrif is located at: http://service.o2.co.uk/IQ/SRVS/CGI...ond hand iPhone,question=ref(User):str(Mobile) click on 'Pay monthly' then the question 'I’m a O2 Pay Monthly customer and have been given an original iPhone, what are my options?' then there is a link 'Transfer tariff form'. So although you WILL have to pay more upfront (to get the iPhone off ebay) the length of your contract does NOT change and so you might even finish your contract in time for the next iPhone!
