HTC, manufacturer of Windows Mobile powered PDAs and smartphones launched itself as a brand 
in the UK around a month ago. At the time, HTC announced two new handsets, and first under the microscope is the ‘TyTN’ – pronounced ‘Titan’. While this SMS-inspired spelling seemed clever at first, it’s getting to be a bit of a pain.
As a device though, the TyTN itself though is far from a pain. If you read Riyad’s reviews of the T-Mobile MDA Vario and the Orange SPV M5000 you are half way to understanding what the TyTN is all about because it is MDA Vario in size and shape but with the SPV M5000s 3G capability.
Both the MDA Vario and SPV M5000 are made by HTC and the company is continuing its strategy of doing deals with operators so that they can provide subsidised handsets.
So if you would like the TyTN after you’ve read this review you have three possibilities: buy sim free from a vendor like Expansys (very expensive and the reason for the low Value rating), take one of the Expansys options that includes an operator tariff, or keep your eye on your favourite operator for a few months to see if they start to stock it.
