It's a shame that Apple didn't (ok, they probably did but nevertheless) check with J.D. Power and Associates and Consumer Reports on Cingular's performance. Cingular rates almost at the bottom in everything while Verizon and Alltel are at the top. Contrary to the "leading independent research company" saying that they have the fewest dropped calls.
I pulled this of Wikipedia:
During the first quarter of 2006, Telephia reported that during an extensive nationwide test of major wireless carriers, Cingular Wireless dropped the fewest number of calls across the country. Cingular in turn began advertising with more aggression the "Allover Network" citing Telephia as "the leading independent research company." This was in stark contrast to the Consumer Unions published "Consumer Reports" which slammed Cingular for static and dropped calls and J.D. Power and Associates' findings. (J.D. Power and Associates consistently puts Cingular in the bottom (or near the bottom) of their "overall customer satisfaction" list.)
Telephia initially refused to provide details on its study, and a spokesman for the company has said, according to the Boston Globe, that "Cingular shouldn't have even mentioned the company's name to a reporter."[12] The research company later stated that Cingular had a "statistically significant lower dropped-call rate than the competition across some market/time period groupings," but that Telephia had "no knowledge of the specific methodology... Cingular used to reach the nationwide 'lowest dropped call' conclusion."
I can understand Apple's rationale since Cingular has the largest customer base (59 million), but in reality, it's only got about 1 - 2 million more customers than Verizon (57 million).
While I will admit that Verizon does cripple its phones, I'd hedge my bets that they wouldn't have done that to the iPhone since it would be such a big deal to get it on their network.
The only thing that I can think of is that they went GSM so they could sell it globally, which does make sense, and since they went GSM they went with Cingular because they have such a large consumer base compared to other U.S. GSM companies.
Ok, my rant is over.
