The R900 was announced back in March at CTIA by pre-paid carrier MetroPCS, and the cost-conscious carrier stated it would have the device out before the end of the year. The Samsung device will contain a 1700/1900 MHz LTE radio (MetroPCS is licensed to operate LTE on this spectrum) Bluetooth, and Wi-Fi.
There has been no indication of what operating system the device will run, although Android is a pretty solid bet.
