Small excerpt from the article makes a decent executive summary regarding Sprint's network performance with the iPhone 4S:

"AT&T is fast and Verizon is everywhere. Where does that leave Sprint? Well, Sprint is the only one of the three carriers that offers an all you can eat program for iPhone 4S users. Yet, the service appears to be so poor that it might not be worthwhile. Is it something inherent within Sprint's network?"
