"Rather like a colour change, the T-Mobile version of the HTC Diamond doesn't really change much from the Diamond offering. In fact the only reason to opt for this variant over the original would be a preference in the casing.
HTC has created a device that is a great iPhone alternative and offers those not keen to switch to Apple or O2 the chance to get touchy feely with their phone, although the new BlackBerry Storm from Vodafone might also appeal.
Against the iPhone the tech specs are better but that stylus inclusion is an admittance that the icons on the screen are just a little bit fiddly from time to time. Overall though, HTC has somehow managed to take the Microsoft OS and make it everything but - a good thing in our mind.
It's a thumbs-up from us."
