With Microsoft planning to release an overhauled version of Windows 8 over the summer, some may be wondering when the company will give a similar treatment to its Windows Phone 8 mobile operating system. The answer, says ZDNet’s Mary Jo Foley, is likely not until 2014. Instead, Foley’s sources say that Windows Phone users can expect three smaller updates to roll out throughout the rest of 2013 in preparation for a more substantial update sometime next year. These updates will include “support for CalDAV and CardDAV, so that it will continue to work with Google contact and calendar syncing services” and will “reintroduce support for FM radio… a feature which was part of the Windows Phone 7 operating system platform, but which was cut for Windows Phone 8.”
