T-Mobile has unveiled an exclusive re-branded version of HTC Touch Diamond 2, dubbed the MDA Compact V, as it looks to grab a larger share of the market for high-end handsets.
The smartphone will run on Windows Mobile 6.1 and will be available on the UK mobile phone network from May 21st.
As part of a move to drive sales of the handset, T-Mobile is giving all buyers of the MDA Compact V a free seven-day trial of the CoPilot satellite navigation software that comes pre-installed.
Meanwhile, from June 1st the first 10,000 customers to purchase the handset on 18-month contracts will get free access to the service for the duration of their contract.
Features of the MDA Compact V include a five megapixel camera, a media player, a 3.2-inch touchscreen and advanced e-mail functions.
T-Mobile is believed to be gearing up for a host of high-profile handset releases this year, including a second Android-powered phone, the T-Mobile Bigfoot.
The network was the first UK carrier to offer an Android handset when it launched the T-Mobile G1 late last year.
