Before iPhone 4, we have 3GS, 3G & 2G but seem they (3GS, 3G & 2G) don't have any model for CDMA network!! is that correct?
So CDMA users (who use Verizon, Sprint, Nextel, Cricket and Alltel carriers) can't use iPhone til iPhone4 which has a model support CDMA? Is that correct?
I am doing a research about iPhone, so i need to know the history of its.
