said by rradina: Apple is using the standard CDMA approved and very popular Qualcomm chipset in the iPhone 4S. Qualcomm is the designer of CDMA and essentially every CDMA phone is digital by Qualcomm.
If this was the FIRST smart phone to hit Sprint's network, I might agree. However, there's nothing revolutionary here as other smart phones don't have the problem. That means someone didn't spend the necessary time on configuration management. Clearly, it's a config problem unless the chipset Apple chose required completely new drivers. (That would be dumb but par since Apple is very closed and likely doesn't like to pay licensing fees to another tech company that knows Sprint's network.)
