Smartphone maker HTC has reported a 41% sales increase for the first six months of 2010.

Year-on-year revenues to the end of June increased from US$2.1 billion  to US$ 3 billion.

HTC previously specialised in making phones branded for specific mobile networks, such as O2's XDA smartphone.

It is also the manufacturer behind Google's Nexus One phone.Whilst HTC continues with that business, it is expanding its own brands, such as the HTC Desire.

Many of the firm's smartphones rely on the Google Android operating system, which rivals the Apple iOS, used in Apple iPhones.

On the Taiwanese stock exchange, shares in HTC closed up 5% at 495 Taiwanese dollars (US$15).
