Windows Phone 8.1 Preview updated to version 12393

It’s just after 1PM ET, and Microsoft’s servers are blazing with a hot new update for Windows Phone 8.1. The update will bump the OS to version 8.10.12393.890 and it's about 21 MB in size, though what changes the update includes is currently not known. This is the second update to come out for Windows Phone 8.1. The first update for Windows Phone 8.1 came in mid-May and introduced battery improvements. 

Want to grab the update? Head into Settings > Phone Update > Check for updates to get the latest.

We’ll update this article as more information comes in!

Update: For some, the Windows Phone boot screen has now changed from left to right (as seen above) for some users, which matches the Lumia 630. Other previously had the boot screen on the right, so may not be new for some of you.

Thanks, everyone for the tips!
