Google announced yesterday (at the last minute) that Google Sync Support for Windows Phone will be available till 31st December. Before this announcement was made, yesterday was the last day anyone could connect their WP devices Google Sync.
Thankfully, Google decided that wasn’t a good decision, and now all the WP devices have enough time to get the GDR 2 Update, and Google Sync can then be replaced by CalDAV and CardDAV.
