Lokkju Brennr lokkju at gmail.comI'm running a C117 on PCS1900 with no problems, in the USA. It was an old Tracfone I fixed the bootloader on and re-flashed. I have no idea if PCS1900 type C117 phones are widely available - but I do know they exist. Interestingly, I recently saw one in the local Walgreens for $20, brand new.
