Windows Phone users who want to use Google Sync for contact and calendar integration had better act quickly: today is the last day that they can link their handsets to the service before Google pulls the plug. From August 1st onwards, Google Sync will only work on a given Windows Phone if it’s already configured. The GDR 2 upgrade keeps syncing alive through CalDAV and CardDAV support, although many users could go without that support for some time — to date, Americans can only see the OS refresh on the HTC 8XT, Lumia 520, Lumia 925 and Lumia 1020. If you’re not in that group and miss the Google Sync deadline, you’ll just have to sit tight while Microsoft finishes rolling out the GDR 2 update this summer.
