Microsoft yesterday released the next version (V 7.5) of its smartphone operating system, code named Mango, which brings many features to Windows Smartphones which previously only found on Android and Apple smartphones.

The software giant says Mango has more than 500 new features including an upgraded web browser for faster internet surfing, the ability to tether, a new Windows Marketplace and a new app called Find My Windows Phone.

The success of the Mango is critical for Microsoft as Windows 7 is struggling to gain a serious foothold in the Smartphone marketplace. According to a Gartner report released last month, Microsoft sold just 1.7 million Windows Phone 7 devices in the second quarter of 2011. Microsoft's share of the global smartphone market was just 1.6% in Q1 2010 vs. 43.4% for Android and 18.2% for Apple.

According to the Microsoft website, the company has started to send updates to Bell Mobility, Sasktel, Rogers Wireless, and Telus Mobility customers. Microsoft says the software updates will be sent out gradually in batches so it might take several weeks before you receive notice that an update is available for your phone.
