File this one under rumor, but an AT&T Community Manager for the AT&T help forums is stating that the Windows Phone 8.1 update may begin to rollout at on "certain devices as early as this week!". The AT&T employee then directs users to watch for an update on the AT&T Consumer blog, where the company usually posts details about such events.

The Community Manager named 'ATTMarianaCM' revealed the news and marked the thread "solved," effectively ending the help topic (though the thread is still open for comments).

Microsoft – and the old Nokia team who oversaw updates – started rolling out Windows Phone 8.1 only last week. Since then, there has been a limited issue with those running Windows Phone Preview for Developers and who have corporate phones with BitLocker enabled. However, the overwhelming majority of updates are going without incident. So far, only the Lumia 625, Lumia 925 have received updates with trial rollouts for the Lumia 1520 in Finland and India (there is also one Lumia 520 in France getting it too),

Despite public perception, AT&T has been in the past relatively timely for OS updates. For instance, the AT&T Lumia 1020 received Lumia Black well before other devices around the globe last December. Likewise, the Lumia 820 and Lumia 920 both had their Lumia Black updates in late January, beating both Verizon and T-Mobile by substantial margins.

It now looks like AT&T may continue that trend by pushing out Windows Phone 8.1 and Lumia Cyan to their customers just one week after the initial rollout. The only question that remains is which devices go first. AT&T has numerous Lumias to support, including the Lumia 520, Lumia 820, Lumia 920, Lumia 925, Lumia 1020, and Lumia 1520. Additionally, AT&T also has the Samsung ATIV S Neo and the HTC 8X, though Samsung and HTC so far have been quiet about any Windows Phone 8.1 updates.
