Twitter, Flixster, Netflix Demoed on Windows Phone 7 [Video]

Microsoft has finalized the Windows Phone 7 Developer Tools and released demos of Twitter, Flixster, Netflix and more.

The Windows Phone Developer Tools have gone final, and we have released to the Web. This release is English only, but we will be releasing the French, Italian, German and Spanish language versions in the next couple of weeks.

For developers to put their apps into the marketplace, opening in early October, you will need to download this version of the tools. Any application built with a previous version of the tools will fail application certification in the Marketplace. When you do submit your application, you can expect it to take about five days to pass or fail certification, though you can check the status of your app submission at any time at the developer portal.

Take a look at few demos of popular applications expected to launch alongside Windows Phone 7 below...
