Yesterday we told you that some Windows Phone 8 users are experiencing issues with their devices. Now CNET is reporting that Microsoft knows about the issue and is investigating it. Aside from the random rebooting madness, some users have also reported that they’re also getting email sync issues with the new OS. Some anecdotal evidence point to Skype Preview being the source of strife, although some users who have the issues say that they’ve experienced the problems without the app installed. The good news here is that the firm from Redmond is now aware of the issues and are trying to look for a fix.
