Picture of the HTC handset, said to be called the HTC T829, have leaked out and, unless some good-quality Photoshop trickery’s involved, a series of pictures online show the device connected to a wireless network at 13.8Mb/s. This is a wireless speed that far surpasses the connection capabilities of HSDPA 3G, which top out at no more than 7.2Mb/s.
Various icons on the mysterious HTC device also appear to show it connected to a network called Yota, Russia’s 802.16 WiMax network that – as of early October – covered central Moscow.
Another picture shows how the phone’s WiMax connection can be switched on and off at will.
In addition to WiMax connectivity, the T8290 is also rumoured to be able to connect over 802.11g Wi-Fi networks. Although it would be disappointing if the device couldn’t connect over 802.11n.
The phone’s said to have a 3.8in, 800 x 480 display and sport Bluetooth 2.0 connectivity too.
Please don't mix this HTX with Nokia N80 WiMax capable series , as the Nokia N770/800/810 are Personal Internet Communicator and not Mobile phone (in other words, they dont have GSM module)
