The 3g iPhone is due to be released sometime this summer, almost a year after the original model came out. A few weeks before the 3g iPhone is released supplies of the old model will dry up; this should, if Apple’s plan goes to plan – leave a lacuna in supplies of the gadget which in turn will fuel a greater demand. Then, bang. Out comes the new model.

Once the new 3g iPhone is out no doubt looking sleeker than ever (it is rumored to be 2.5mm thinner than the current model (which is pretty darn thin)), AT&T and Apple will offer the new model with a massive $200 price cut. Make this deal available to new customers that have to sign a two year deal for the service provided, and you’re on for a financial success story.
