GDR1Last we reported about a new Windows Phone 8.1 build and the reported version 8.15.12375.0 was a big jump from the latest Windows Phone 8.1 update 1 build 8.10.14157.200. Now, it was easy to guess that it may belong to the second major Windows Phone 8.1 update which may be termed as GDR2 or Windows Phone 8.1 update 2. The GDR2 dev preview has been marked for October by our sources, but don’ get surprised if it happens sooner than that.

Today we spotted a slightly higher version 8.10.14160.0 at WPBench, as compared to latest Windows Phone 8.1 update 1 developers preview build, 8.10.14157.200. Comparing the two versions, it very well looks like the second update for Windows Phone 8.1 update 1 and it may be coming soon.

The last update to Windows Phone 8.1 update 1 didn’t bring any visible change, so it will be interesting to see what comes with this second update.
