The first LTE phone approved by the FCC is the Samsung SCH-R900
It is a dual-mode CDMA / LTE handset, with the LTE capabilities shining on the 1700 / 1900 radio bands. Wi-Fi and Bluetooth are also in there. Considering Verizon's LTE efforts, the phone will probably need a SIM card as well. Come on, future, arrive already, eh?
