Besides admitting the issue on its support forums, Microsoft said that it would send out a fix. Unfortunately, the software giant did say that it wouldn't be rolling it out as fast as Windows Phone 8 users would want it to be. Microsoft said that it could not commit to a specific time for sending out an update to repair the issue.
A moderator in one of the support forums, promised to pass along the latest news on the issue next Thursday. While most of those complaining about the error message are sporting the Huawei Ascend W1, Microsoft admits that the error message appears on other models as well.
