If you were wondering what the difference between Sprint, Verizon and Cingular's high speed cellular data network was, you've come to the right place. A Sprint employee did a comparison of the three, pitting them in a deathmatch based on coverage, performance, terms of service, and pricing.
The results? Sprint was ahead in coverage, with 155+ markets served. Verizon came in second with 95+ and Cingular with 16+. In speeds and terms of service, they were all about the same, give or take. You're not going to be able to run VoIP and other high bandwidth stuff off of their network. There's not even a huge gap in terms of price either, as all of them are in the $40~60 range.
So what's the big difference? EV-DO RevA is rolling out slowly, which puts Sprint and Verizon ahead of Cingular's HSDPA, which also has less coverage than the other two. And Sprint has the most "unlimited" usage, which doesn't kill off your plan if you go over 5 or 10GB of data a month. As you would have guessed (since the guide is from a Sprint employee), Sprint comes out the winner.
