Update for Windows Phone 8.1 Developer Preview Rolling Out
Microsoft have started rolling out an update for the Windows Phone 8.1 Developer Preview, which should bring with it bug fixes and stability improvements.
The latest build, 8.10.12382.878 can be installed on your developer unlocked device in the usual way, go to Settings then scroll down to Phone Update and then click “Check for Updates”. The update is around a 22mb download. And if you have been having problems with your Windows Phone running 8.1 Developer Preview I hope this sorts it out.
The official 8.1 update, known as Nokia Cyan for Lumia devices, should start rolling out in June or July.
