Windows Phone 7 app partners, marketplace, Netflix prototype shown

Microsoft held a Windows Phone 7 blowout event today, revealing details about the new interface, games, and apps for the upcoming mobile OS. Among the software shown was a repeat of the coup it perpetrated on Xbox, namely a Netflix app for its mobile OS that includes Instant Streaming. Neat!

In addition to Netflix, Microsoft listed a bunch of companies that have signed on for Windows Phone apps. Names like Hudson, EA Mobile, PopCap, and Foursquare should be familiar to iPhone users — as, we're guessing, should be the apps these companies put out.

Microsoft also revealed how you'll buy these and other apps: through a new Windows Phone Marketplace, which will also allow developers to set trial periods for their downloads.
