BenQ Mobile introduced six new mobile phones under the BenQ-Siemens brand at the CeBIT trade show in Germany, including the P51, a quad-band GSM/EDGE device running Windows Mobile 5.0.

The P51 features 802.11b/g Wi-Fi and has Skype pre-loaded so that users can make VoIP calls over Wi-Fi. It also has a Qwerty keyboard, a 2.8inch quarter-VGA screen, a GPS receiver, 128MB of memory and an SD slot for expansion.

The Windows Mobile software includes Powerpoint and voice control, and it allows users to receive push e-mail from their corporate e-mail accounts. The P51 is expected to become available in the third quarter.

The EL71, another new handset, is a triband slider phone featuring a metal finish and designed for the "young professional," BenQ-Siemens said. Other new handsets include the CF61, a consumer-oriented phone with a music player, Bluetooth and exchangeable covers, and the C81, a multimedia phone with a larger-than-usual speaker for better audio, the company said

BenQ-Siemens will pre-install a Google search bar on some handsets. The announcement follows similar deals over the past few months between Google and other handset vendors and operators.

It also launched a service that will allow customers to wirelessly update the software on their phones. This will provide people with more ways to configure and personalise their phones, the company said.
