Stephen Elop has just taken the stage at AT&T's Developer Summit here at CES, taking the opportunity to confirm that an LTE-enabled Nokia Windows Phone will indeed be heading to the carrier. The exec didn't offer too many details beyond that, but promised to reveal more at his company's event this afternoon, scheduled for 6 PM ET / 3 PM PT. Could it be the Lumia 900 we've been expecting? We'll have to wait a little longer to find out, but will be sure to keep you posted as soon as we hear more.
