SAN JOSE, Calif., Oct. 26 (AP)  Apple no longer accepts cash for iPhone purchases and now limits sales of the cellphone to two per person in a move to stop people from reselling them.

The new policy started Thursday, said Natalie Kerris, an Apple spokeswoman. Before then, there was no cash restriction and the purchase limit was five per person.

“Customer response to the iPhone has been off the charts, and limiting iPhone sales to two per customer helps us ensure that there are enough iPhones for people who are shopping for themselves or buying a gift,” Ms. Kerris said. “We’re requiring a credit or debit card for payment to discourage unauthorized resellers.”

More than 1.4 million units of the hybrid cellphone-iPod have been sold since it was introduced June 29, according to Apple. It is expected to be a popular gift for the holidays.
