According to Bloomberg’s Connie Guglielmo, “Wal-Mart Stores Inc. will become the second mass-market retail chain [after Best Buy] to start selling Apple Inc.’s iPhone, with two store representatives saying the world’s largest retailer will carry two models of the Web-surfing handset this month.”

Guglielmo reports, “Employees in the cell-phone departments at five California stores, contacted by phone today, said Wal-Mart will offer iPhones by the end of December. Employees are currently being trained on how to sell the device, all five said… Apple currently sells two models at $199 and $299.”

Guglielmo reports, “A clerk at a Wal-Mart store in Vacaville, California, said the store will sell the 8- and 16-gigabyte models at the same prices as AT&T, or $199 and $299, respectively. The person, who declined to give his name, said the phones will be available Dec. 28.”

Troy Wolverton reports for The San Jose Mercury News, “Bay Area Wal-Mart Stores will have the iPhone in stock by the last week of December, and maybe before Christmas, said managers and employees at several stores.”

Wolverton reports, “Some Web news and rumor sites recently reported that Apple will offer a special 4GB version for $99 through Wal-Mart. Most Wal-Mart employees contacted Friday either didn’t know about such a model or said that Wal-Mart would not be carrying one.”
