AT&T will feel pretty good about iPhone speed tests which help confirm the claim that the carrier has the nation’s fastest network.

Ookla, which is known for its online broadband test at Speedtest.net, offers a Speedtest.net app for the iPhone which not only lets users collect data about their upload and download speeds, but also captures the results of all tests so they can be compared. These results have allowed Ookla to offer a side-by-side comparison of the network speeds experienced by AT&T and Verizon Wireless iPhone users.

The AT&T iPhone user experience offers an average download speed of 1,769 Kbps and an average upload speed of 730 Kbps. Verizon Wireless iPhone users on the other hand saw an average download speed of only 848 Kbps and average upload speed of 506 Kbps.

While upload speeds are closer together, AT&T’s download speed was double that of Verizon. The data set for the results included 43,000 AT&T and 14,000 Verizon Wireless iPhones across the country. Over 106,000 tests were run on the AT&T iPhone compared to 49,000 tests conducted on the Verizon iPhone, indicating that most users ran the test more than once.

Doug Suttles, co-founder of Ookla, points out that the results shouldn’t be too surprising for consumers. That’s because AT&T has been known to tout its network speed while Verizon Wireless has focused its marketing on its coverage and the reliability of connections. At the end of the day, customers are going to choose their iPhone based on what is more important: download speed or reliability and coverage.
