T-Mobile has started taking pre-orders of the HTC Desire ahead of the handsets sale date.
The Desire will be the third HTC handset to launch on the operators network since October 2008.
The phone will be HTC's first handset to use the 1Ghz Qualcomm Snapdragon processor and will eventually be available through all operators and retailers.
HTC's executive director of UK and Ireland, Jon French told Mobile at Mobile World Congress: 'We will take a very bold stance in the market, particularly with the Desire'.
T-Mobile confirmed that the pre-orders had started and although it was unable to confirm figures, but said initial interest was high and predicts it is going to do well.
The operator continues to add Android handsets to its portfolio. Other Android handsets that are being added to the portfolio include: the LG inTouch Max GW620, Sony Ericsson Xperia X10 and the Pulse Mini manufactured by Huawei.
T-Mobile MD, Richard Moat told Mobile at Mobile World Congress the idea was to provide 'a range of Android smartphones at different price points'.
The handset is due to go on sale in T-Mobile stores on 29 March and will be on sale in Orange and other operators shortly after.
Last week, Carphone Warehouse revealed the tariffs the handset would be available on. T-Mobile tariffs start at £25 a month for 18 months with the handset costing £179.99.
For a £35 a month contract over 18 months customers can get 900 minutes, 500 text messages and unlimited data.
