Toshiba has unveiled a new smartphone which the manufacturer hopes will be a viable alternative to Apple’s iPhone 3G and the like. Dubbed the TG01, this Windows Mobile 6.1 handset is just 9.9mm thick and boasts a large 4.1-inch WVGA 800 x 480 384k pixel resistive touch screen, alongside features such as HSDPA and Wi-Fi connectivity, GPS, 3.2 megapixel camera, Bluetooth and a microSD slot. It will also come with a completely redesigned (and rather ugly) user interface to make navigation easier.

But while its exterior design and features may be attractive, the most appealing part seems to be what’s under the hood – it uses Qualcomm’s 1GHz Snapdragon chipset. This much awaited system-on-a-chip is said to support 720p video decoding, 3D graphics and a dynamic speed control feature to lower clock speeds when performing light tasks in order to conserve battery life. In other words, the TG01 is a pretty capable smartphone and could double as a powerful mobile gaming platform as well – if developers notice it of course.

Toshiba said that the TG01 will be available in Europe over the summer but gave no details regarding carriers or even a price. Hopefully more details will come out at the Mobile World Congress later this month. In the meantime, you can check out a video of the device in action after the break.
