It was just a few days ago where an MSDN forum thread prompted a response from Mark Chamberlain, Microsoft Principal Developer Support Escalation regarding the Windows Phone 7.8 Tile issue. The problem stems from some Live Tiles not getting updated or using too much data, neither of which are viable options for must users and is one heck of a bug to slip.
Last night, Microsoft’s Joe Belfiore, who leads the Windows Phone Team, even acknowledged the issue on Twitter. Responding to a question about static tiles, Belfiore noted that “We identified a minor issue where some 7.8 tiles stop updating and we are working on a fix now”.
What form that update takes is anyone’s guess as presumably it will require an updated OS and not just a software patch. Since Windows Phone 7.x doesn’t do over-the-air upgrades like Windows Phone 8 does, apparently this will be a little trickier.
Windows Phone 7.x users will also require some sort of OS update to address the Google Gmail CardDav and CalDav login issue, which is set to expire mid-year for current users. So far it is not clear if Microsoft intends on lumping that fix into one for the Live Tile problem.
