A new 3G Pantech phone has been spotted on the FCC site, and it looks to be the Pantech C600. The quad-band GSM/EDGE/UMTS device is a clamshell with dual color displays and a camera. Not much else to go on, but this would mark the first UMTS 3G Pantech phone for the U.S. market and may be out some time this year.
