Reuters inform: “AT&T Inc said on Monday delays in activating service for customers of Apple Inc iPhone had been mostly resolved after the wireless company worked out the problems on a case-by-case basis.”

“Activation delays stemmed from large customer volumes and problems with customers trying to transfer corporate cell phone accounts to personal iPhone service accounts, AT&T said on Sunday.”

“AT&T said that iPhone sales for the weekend were the strongest of any device in the company’s history. Bill Shope, who covers Apple for JP Morgan, estimated in a research note that 312,000 iPhones were purchased on Friday and Saturday.”

“Other strong selling phones at AT&T have included the Razr phone from Motorola Inc, which helped boost sales at both companies for years. AT&T was the first provider to sell Razr when it went on the market in late 2004.”
