After weeks of rumors, it’s been confirmed that Apple retail stores are limiting sales of iPhones to two per customer. Store employees have also been instructed to accept only a credit or debit card for iPhone payments–no checks or cash, the policy states. Those expecting to skirt the policy by buying from different Apple stores will find that their purchases are tracked by Apple’s payment system, and over-limit purchases will be refused. Apple spokesperson Natalie Kerris told the Associated Press the policy is intended to insure a supply of iPhones into the holiday season. However, past customer buying accounts seem to indicate the policy may also be intended to prevent the purchase and shipment of of iPhones to other countries, including Canada and Russia.
