Now that sufficient quantities of iPhones are in circulation, Apple recently raised the limit that customers can purchase from two to five. SetteB.IT reports that out of the 1.4 million sales in the US, 18-percent have not been registered with AT&T, which the company assumes are currently in Europe for the most part. Originally, customers paid with a credit card, and Apple would use this to ensure that no more than two iPhones would be sold to the same person. The iPhone is available through either the wireless carrier or Apple's stores in the US and Great Britain, but French and German customers have to purchase their phone from Orange and T-Mobile stores, respectively.

Apple is steadily unveiling the iPhone all over the world, with Canada and China currently under scrutiny, and rumors regarding the state of arrangements Apple has with carriers in those countries running rampant.
