Microsoft launched the Windows Phone Marketplace back in November 2010. Today they revealed on the Windows Phone Developer Blog, that they are very close to pass 30,000 apps.

Windows Phone Marketplace is growing almost as fast as Apple’s App Store did, which reached 30,000 apps in about 8 months. For comparison, Google’s Android Market used nearly 17 months to reach the same milestone.

Microsoft has also begun accepting and certifying apps for Mango , the first major update for Windows Phone 7. This means that all updated apps will get support for new features like fast app switching, background audio, multiple and double-sided Live Tiles, better Search integration, and more.

Below is a quick look at Windows Phone 7 Mango, technically known as Windows Phone 7.5.
