GSM vs CDMA
Does the deciding factor also include whether the carrier's radio service is GSM or CDMA or some other type?
I seem to notice this when I went phone shopping with US carriers. Is Sprint more expensive because its radio band is CDMA and Cingular is cheaper than Sprint 'cause Cingular uses GSM as a bandwith.
I am really confuse on this, and why some US carriers charge more for services than others? Insight anyone?
