There is nasty rumor in the wild that when we will see Windows Phone 7 final release, even there is no official details unveiled during Mobile World Congress 2010. Windows Phone 7 is the next upcoming version of Windows Mobile operating system which has been planned to release by this October.

Lets explore, what’s going on behind the scene. Brandon Watson blogged and congratulated to Windows Phone 7 team to accomplish an amazing job of delivering code month after month on path to releasing later this year. Check out this timeline:

• Feb 2010 – Windows Phone 7 was unveiled at Mobile World Congress in Barcelona
• Mar 2010 – The application platform was unveiled at MIX 10 in Las Vegas.  With that, we had the first CTP of the Windows Phone Developer Tools.
• Apr 2010 – The tools received an updated, and the CTP Refresh shipped.
• Jun 2010 – Windows Phone Marketplace details unveiled at TechEd 2010.
• July 2010 – Beta release of Windows Phone Developer Tools, and the preview developer phones start shipping to ISVs

Brandon Watson says:

We made a promise last month that we would be getting pre-production preview devices to developers this month. We are keeping that promise. In fact, the very first preview devices were awarded last week to a pair of pretty amazing high-school students who won the Windows Phone “Rockstar” contest as part of the Imagine Cup. Starting next Monday (July 19th), we start shipping the devices more broadly.
