Apple's website has now listed the pricing for an unlocked iPhone 5, but has not yet announced a date for US availability. All three sizes of iPhone 5 will be available to be purchased outright, which gives users the freedom to use them internationally as well as sign up for prepaid service rather than obligating them to contracts. Canadian buyers will be able to pre-order the full-price model, but will pay $50 more for the device -- despite the fact that the Canadian dollar is roughly at par with US currency.
