WP8.1 GDR1Microsoft has announced that a new update will start rolling out to devices running developers preview version of Windows Phone 8. update 1. As promised by Joe Belfiore, this update will bring fix for the error 0x80188308 and will enable HTC devices HTC 8X and 8S to update to GDR1.

Build 8.10.14176 starts rolling today to developer preview participants, and provides a bunch of performance improvements and general fixes. One of the important fixes addresses an issue some folks were seeing during the update process – the 80188308 error – which resulted from running out of storage space in the system partition during update. We expect this fix to solve the update issue for most users.

We can consider it as a preparatory update before Windows Phone 8.1 update 2 aka GDR2 finally rolls out to dev preview devices.
