Two anonymous sources have spoken to a pair of outlets that may have confirmed the Nokia Ace, also known as the Lumia 900, coming to AT&T. Both Bloomberg and the New York Times received very similar information, possibly from the same contacts, that the flagship Windows Phone would be launched on AT&T at CES next week. The former trade publication supported beliefs that it would carry 4G LTE and understood that AT&T was aiming for $249 on a contract.
