Apple has posted a support document outlining the differences in calling features between the GSM and CDMA models of iPhone. As the document notes, “depending on your wireless carrier’s network technology (GSM or CDMA), there are different methods for enabling and using” many phone features.
The list of features includes call forwarding, call waiting, caller ID, conference calls, inserting pauses when dialing, and hold. Notably, the GSM model of iPhone supports up to five calls simultaneously in conference call mode, while the CDMA model supports only two, and doesn’t offer support for placing a call on hold, while the GSM model does.
