ZTE has unveiled the Tania, its first smartphone to run the Windows Phone 7.5 platform.

The white handset, which measures 129x68x11mm and features a 4.3in touchscreen, is powered by a 1GHz processor and comes with 4GB of internal storage. Windows Phone 7.5 Mango allows users to access their Xbox Live accounts from the handset, as well as open and edit Microsoft Office documents and even stream music thanks to Microsoft's Zune service.

The ZTE Tania also comes with Bluetooth, 3G and Wi-Fi connectivity, along with the ability to act as a Wi-Fi hotspot for other mobile devices. Other features include an FM radio, compass and Assisted-GPS (AGPS).

"We're delighted to be working with Microsoft and as a key partner will support the industry forecasted growth on this exciting new platform with both the ZTE Tania and in the future a growing range of devices," said Wu Sa, director of mobile device operations at ZTE UK.

ZTE claims the Tania is the "most affordable 4.3in screen Windows Phone on the market" with prices expected to hover around the £10 to £20 mark on contract. However, while the smartphone manufacturer confirmed Virgin Mobile would be among those carrying the device, it has yet to reveal a UK release date.

According to Clove, which has the handset listed for £249.99, the first shipping date is February 13. The handset has been listed as available to pre-order on the site since the beginning of January.

"Having ZTE join the Windows Phone family is great news. Their expertise will be crucial in delivering Windows Phone to new and different customers. We look forward to continuing and developing our relationship with ZTE in the future," added Leila Martine, director of Windows Phone UK.
