AT&T Limiting iPhones to ONE Per Customer, No Cash or Checks

AT&T just sent out an internal memo to its employees today limiting all iPhone purchases to one per customer—down from a previous three—and making everyone pay with credit cards or debit cards. Do they want to make their stock last until the 3G iPhone is out? Probably, since people who buy more than one are usually not regular guys who just wants to use the phone for themselves.
