A few weeks ago, Microsoft posted a note on its Windows Phone blog telling owners of Windows Phone devices that very soon, they will have to update to Windows Phone 7.5 if they want to continue to download apps from the Windows Phone Marketplace. This week, Microsoft posted up yet another reminder on this event on its official blog.
According to Microsoft's Mazhar Mohammed, "We’re now doing the final work needed to turn on this new requirement, so I thought it would be a good time for another friendly reminder." While the blog does not offer a specific date for when this change will happen, Mohammed does say he will post another note on the day when the Windows Phone 7.5 requirement for the Windows Phone Marketplace actually begins.
In April's post, Microsoft said, "Requiring Windows Phone 7.5 is part of an overall effort aimed at improving Marketplace performance and security, and paving the way for even faster growth and more new features."
Some of the people who posted comments on this week's blog post are complaining that their wireless carrier doesn't yet offer the latest Windows Phone software update. In particular, the long running "disappearing keyboard" bug seems to be an issue for many Windows Phone 7.5 users.
