Microsoft to send out update to fix 80188309 error that prevents Windows Phone 8 users from updating

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.
"The update itself is not going to be available today, or likely early next week. We will continue to work on getting you this update but it will not be as fast as you would like. I know a lot of you would like a better timeline on when it will be available, and at this time I cannot commit to a date."-Moderator on Microsoft support forum
