Apple Documents The Differences Between GSM and CDMA iPhone 4

For long now, Apple has been doing only GSM versions of the iPhone. But, the release of Verizon iPhone 4 has seen the advent of the CDMA iPhone 4. In order clear user’s confusions about the differences between GSM and CDMA devices, Apple has now come up with a document detailing the differences in the functionalities of the two devices.

The first and foremost difference between the two devices is with regards to call forwarding, caller ID and call waiting. On the GSM handsets, these features can be turned on or off by going to the Settings panel, while on the CDMA handsets, this has to be done by dialling in a number combination. Another difference is with regards to conference call. On the GSM sets, up to 5 people can connect via conference at once, while the CDMA set allows the numbers of only two users. Pausing a call is possible on the GSM handsets and there is no such option on the CDMA handsets.
