A few days ago, the Windows Phone community was elated to hear that the long-awaited Windows Phone 7.8 update is nearly upon us. A report claimed that AT&T would be the first to offer the update to millions of Nokia Lumia 900 owners, and today there is new evidence to support your anticipation for tomorrow.

Engadget has received the image above, an internal AT&T channel communication, from one of its tipsters. The slide just so happens to detail everything the earlier report made note of, but with one key difference: an explicit mention that Windows Phone 7.8 will begin rolling out tomorrow, January 30th, 2013. Unfortunately, no other devices are confirmed to receive the update at this time.

We're less than 24 hours away from what could be the last significant milestone of the WP7 era. Stay tuned for release details and hands-on coverage tomorrow.
