According to a report in the LA Times today, Apple’s new iPhone sold out in many AT&T retail stores and some users had difficulty getting their new phone activated. “Shoppers snatched up about 525,000 of the devices at Apple and AT&T stores from Friday’s launch through Sunday, said Trip Chowdhry, an analyst at Global Equities Research in San Francisco.” The story also notes that half of the Apple retail stores on the West Coast sold out of the new phones on the first day. “AT&T declined to comment on the availability of the device or sales totals, but according to news reports most of its 1,800 stores ran out of stock by Saturday. Chowdhry said AT&T apparently had insufficient technical support staff on hand because it hadn’t prepared for such heavy demand.”
