References have appeared on Microsoft’s OEM site for the next minor update to Windows Phone 8.1, GDR 1. Regular readers will recall that it was the same site which leaked a detailed explanation of how folders will work in the next version of Windows Phone, but in this case Microsoft had locked things down pretty thoroughly. GDR1 is rumoured for an August release, and it seems clear that work on it is pretty advanced. Hopefully the documentation is the very last step, and we will soon see the update live on our handsets also.
