More evidence of Windows Phone 8.1 in testing, may be announced at MWC 2014


WPDang reports that Chinese developers are seeing increased evidence of Windows Phone 8.1 handsets in testing, with build 8.10.12166.0 being detected by some developers

We have last noticed the updated software showing up in June this year, when build 8.10.12076.0. showed up in the wild.

The updated software is expected to feature a notification centre, multi-tasking improvements, a possible unification of the Windows Phone and Windows 8 store and many other updates. reports that the OS may first be shown off at Mobile World Congress 2014, which of course coincides with other rumours of an early 2014 debut.
