After several months of waiting, Microsoft and Nokia have delivered the Windows Phone 7.8 update as promised.
However, it appears that all smartphones that were upgraded to WP7.8 are now affected by a critical bug that will massively take advantage of data usage, thus draining the battery.

So far there have been no reports that the issue might cause huge data usage on devices powered by Windows Phone 8 smartphones. It appears that when a new application is pinned on the start screen, it makes a request to a server for an icon to be put on live tiles and that website is unavailable, causing an endless loop to try and get that data.
