Just over six months after the introduction of Microsoft’s Window Phone 7 mobile phone operating system, the Windows Phone Developer Blog has announced that the gold release of the Windows Phone Developer Tools will be available on September 16th. Along with that news, we have also been informed that application submissions to the Windows Phone 7 Marketplace will begin sometime in early October. There still isn’t a set hardware launch date, at least nothing more than the “ready for the holidays” line that we have seen before, but with the Marketplace ramping up in early October we’re going to set our sights on a late October or November launch date.
