Microsoft took the time out today to detail the upcoming Windows Phone 8 GDR2 update that is aimed at hitting devices this summer. The new update should not be considered as something major, as it only brings to the table upgraded features and a small number of improvements, some of which are very important.

"The new update, which is expected to start rolling out to existing Windows Phone 8 phones later this summer, brings back support for FM radio (we heard you!) and makes the Data Sense feature of Windows Phone 8 available for more carriers to offer. The update also makes it easier to select, download, and pin tunes in Xbox Music and improves the accuracy of song info and other metadata-something I know music fans will appreciate. (FM Radio and Data Sense availability depend on your phone model and carrier.)

The update includes hundreds of other small quality improvements. One final one worth highlighting, as we announced earlier, is that the update also ensures Windows Phone continues to work with Google services by adding support for the company's newest sync protocols-CalDAV and CardDAV," the official Windows Phone blog said.

It is nice to see Microsoft bringing back the FM radio support. It is not a feature used regularly these days due to the availability of the Internet almost everywhere you look. However, there comes a time when the FM radio could come in handy.

Furthermore, it is great that Microsoft is making Data Sense available for more carriers; still, it would be a lot better if the feature wasn't carrier dependent.

Finally, the biggest feature of all, the feature all Gmail users have been waiting for. The new update will bring support for the new sync protocols, CalDAV and CardDAV. Google has made a big deal about this, the company has even dropped support for Microsoft Active Sync in support of this feature, which gave Microsoft no choice but to put its support behind the platform.

Synchronizing your Gmail data should come as no problem after the GDR2 update.
