iPhone 5 on EE 4G: 'less than £10 extra per month' Industry sources suggest that the iPhone 5 will cost £45-48 per month on a 3G tariff on a two-year contract, in line the launch prices for the iPhone 4S. Although the 4S price fell relatively rapidly, the 5 is expected to fall slower as it is a more expensive device. The base model, which will retail for £529, could therefore cost £1080 over two years, rather than £1009 if bought outright and then tied to a £20 per month contract. Although price details of EE's first British 4G services will not be revealed for several more weeks, it is expected that the iPhone 5 will cost less than £10 per month extra on a two-year contract. EE said customers would be able to join its other networs, Orange and T-Mobile, and then upgrade when 4G details a re announced. A new sim card will be provided free of charge. Although Apple retains tight control over pricing for the iPhone, details have not yet been confirmed and could still change. Apple's iPhone 5 is also expected be in shorter supply than its predecessor, as Apple expects to sell more devices in America and the Far East than previously. Apple announced the iPhone 5, its first 4G phone, at an event in San Francisco last night. Showing off the new smartphone, Phil Schiller, Apple's marketing chief said: "We've updated every aspect of iPhone 5."
