Microsoft rolling out new Windows Phone 7.8 update (build 8860), presumably fixes Tile bug

We’re getting our inbox flooded with tips from folks noting that their numerous Windows Phones (mostly unbranded), are receiving a new OS update today, knocking their build from 8858 to 8860. We just checked our AT&T Lumia 900 and did not have success, meaning carrier-branded devices may have to wait a few more weeks.

There is no current changelog with the update though we presume it address the Tile stability issues that were found in the original Windows Phone 7.8 release. Those problems caused occasional Tiles to not update and in other instances, drained too much data. During the Zune Desktop installation, the only key phrase that is in the description is a “quality improvements”, as opposed to new features or additions, strongly suggesting that this is a bug-fix release.

So far it seems mostly those in Europe, including Italy and elsewhere are getting the update. We’ll continue to follow the story as it develops.

Thanks, James D., Roland R., Firdaus M., krox1105, Saurabh A and others for the tips!
