CDMA includes phones on Samsung, LG, Sanyo, and more.
Right now there is no easy way to use CDMA phones. The best option is Bitpim.
You can use the latest version ofAUR for these phones. Make sure you run Bitpim as root and everything should work.
Note: Bitpim is not available in the AUR or the official repositories at this time.
