The HD7 comes with 16 GB of storage and is powered by a 1GHz Qualcomm SnapDragon processor. The smartphone also comes with Wi-Fi support, a built in FM radio, GPS, Bluetooth features and will ship with Netflix, T-Mobile TV, Slacker Radio, Xbox LIVE and Zune software pre-installed.

The device is set to be available from T-Mobile in the US, and from Orange, O2 and T-Mobile in the UK.

The Windows Phone 7 operating system has been labelled by many industry analysts as Microsoft's last attempt to succeed in the smartphone market.

The software giant has pledged $400 million to promote the OS as it enters competition with already established rivals Apple, Research in Motion, Nokia and a multitude of devices running on Google's Android platform.
