It did not take too long after the announcement by Microsoft concerning the availability of the Windows Phone 7.8 SDK (software development kit) for AT&T to follow up that they have the Windows Phone 7.8 update for the Lumia 900 – although it is right now waiting for the command to bolt out of Nokia’s server doors. Listed on Nokia’s servers for the Windows Phone 7.8 update for the Lumia 900 include all color variants of the smartphone, and have been labeled with the 8858 OS build number.

This is good news for Lumia 900 owners, considering how that proved to be one of the higher profile Nokia devices in the past year (before the Lumia 920 was released, of course). Not only that, spotting the updates ready and waiting in the wings would mean that the chances of other AT&T devices getting said update would also be sooner rather than later. A little bit more patience, my young padawan, and you should see your beloved Nokia Lumia 900 jiving with the best that Windows Phone 7.8 is able to offer.
