While this data cable is well-made, it is useless for the Pantech C3B cell phone (as of this review date). The reason? There is no usable software that comes on the included CD for this cable, and there is NO real software that has yet been created for this particular model of phone. The only software that is available, and that is recommended by some people to use with the Pantech C3B and the above PC USB data cable, is for another Pantech phone entirely , and the software will not work properly -- if at all -- with your C3B.
