The HTC Supersonic is supposed to be an Android 2.1 mobile phone that HTC is still working at. This smartphone is said to support WiMAX on the Sprint network in the US when it releases.
WiMAX is a wireless communication technology that allows you to access internet on the go. The radio mast for WiMAX covers a radius of about 30 miles around it. It is thus more powerful than WiFi. However, when compared to mobile broadband (802.20), it offers lesser coverage and also uses the 2-6 GHz frequency range, when compared to the 3.5GHz used by mobile broadband.
The Supersonic is reported to have a large 4.3" touchscreen similar to that of the HTC HD2 which is a Windows Mobile 6.5 phone. There is also supposed to be a stand, like that of the HTC Imagio, which will enable using this mobile phone as a digital photo frame.
The HTC Supersonic is also mentioned to sport the HTC Sense user interface. The Snapdragon processor is said to be employed in this handheld. Therefore, one can expect speedy processing from this mobile handset. A 5MP camera and a 3.5mm headphone jack are also supposed to be present in this device. Other details are sparse right now.
Currently, there's no news, if this smartphone will make it to the UK market with maybe a different name and slightly altered specs.
