HTC has announced a new quad-band HSDPA/GPRS/Edge smartphone that will debut in Europe in September. The underside of the HTC S740 handset slides out sideways to reveal an alphanumeric keypad.

The design of HTC S740 is similar to HTC's popular Touch Diamond handset. The new model is a slim 16mm deep, 43mm wide and 116mm tall. Finished in matt black, the HTC S740 has a 2.4in QVGA display.

Running the Windows Mobile 6.1 operating system, the HTC S740 enables mobile broadband access at download speeds of up to 7.2Mbps. The device supports POP3, IMAP and Exchange push email access.

Other features of the phone, which comes with Bluetooth v2 and built-in GPS, include a 3.2Mp camera with fixed focus, a 256MB internal flash memory and support for MicroSD memory cards.

"Clearly, one size does not fit all. The S740 will play an important role in expanding our growing portfolio of devices," said Dr Florian Seiche, vice-president of HTC Europe.

Pricing for the HTC S740 has yet to be announced. No price has been released for the device, which will be available from September 2008.
