Cingular Wireless and T-Mobile USA have stopped selling the Razr - temporarily, at least. The phone, Motorola Inc.'s flagship, seemingly has a technical glitch that causes the phone to drop calls or shut down. Only a limited number of phones were affected and the problem but Motorola is still selling new Razrs and expects availability to return to normal by next week.

"Motorola and its customers are addressing a quality issue affecting a very limited number of Razr handsets sold for GSM networks," Motorola spokesman Alan Buddendeck said in a written statement.
