Check out the differences between the AT&T and Verizon iPhone at a glance by clicking on the chart aboveSo before you make plans to pre-order your CDMA-based iPhone in early February, let's take a look at some numbers comparing Verizon's speeds to AT&T's. But first a disclaimer. Until PCWorld re-tested the iPhone on AT&T and Verizon's networks everything that follows should be taken with a grain of salt.
How PCWorld Tests
PCWorld and its testing partner, Novarum used two types of tests in 13 cities across the country. The tests included "51,000 separate tests covering 850 square miles of wireless cell coverage servicing 7 million wireless subscribers."
To test 3G speeds, PCWorld "connected to the 3G network [in each city] via both laptops and smartphones. The laptop tests accurately measured the capacity and performance potential of a given network, while the smartphone tests approximated the real-world connection speeds users of these popular devices might experience."
For our purposes, we'll only consider what the smartphone results were since they are more likely to be closer to what you'll experience with an iPhone in your pocket.
Where AT&T Won

In fact, AT&T didn't just beat Verizon in those cities more often than not it trounced its network rival. Among AT&T's fastest cities, its lowest network download speed was in San Diego where the company rated an average of 1075 kilobits per second. AT&T's the fastest city was Seattle at 1751 kbps. In fact only two cities of AT&T's top 9--San Diego and San Francisco--had average download speeds lower than 1200 kbps.
New York was the only city among AT&T's victories where Verizon came even close to measuring up to AT&T speeds. AT&T in New York scored an average download speed of 1233 kbps, while Verizon's average was 1227 kbps.
AT&T in PCWorld's tests also beat out Verizon in terms of reliability defined as the percentage of 1-minute tests during which network service maintained an uninterrupted connection at a reasonable speed.
Verizon did not score above 90 percent reliability in any of PCWorld's test cities, while AT&T's average reliability was above 90 percent in 10 out of 13 urban centers.
Where Verizon Won
What about Sprint?
There's also a rumor going around that Sprint might announce it has the iPhone at a press event on February 7. If you're curious about Sprint's 3G results then you'll be happy to know that Sprint had a few victories in PCWorld's smartphone 3G speed tests. The nation's second largest CDMA carrier had the fastest upload speed in San Francisco at 147 kbps. Sprint also came out with the best percentages for reliable service in Portland (tied with AT&T), San Diego (tied with T-Mobile), San Francisco, San Jose and Seattle.

Has anybody out there recently used smartphones from both AT&T and Verizon in the same city? What's been your experience?
