iPhone 4S (and iPhone 4) Speed Test: AT&T vs. Verizon vs. Sprint

So, the other night, I had the opportunity to test a few phones across AT&T, Sprint, and Verizon.

We had two iPhone 4S and one iPhone 4 phone.

One iPhone 4S was on AT&T, the other iPhone 4S on Sprint, and the iPhone 4 on Verizon.

I was quite astonished by the results of our Speedtest.net test on these phones, all running iOS 5.0.1.

Shocking. The 4S on AT&T was nearly 6x faster than the same phone on Sprint. That made me happy. Sprint has the most liberal data plans from what I gathered, but I’m glad to be that much faster. The sad thing to note her was how poorly the iPhone 4 performed on Verizon.

The Verizon phone had the weakest visible connection with 3 bars, the AT&T phone had 4 bars, and the Sprint phone had 5 bars. This is just for educational purposes. Hope you enjoyed it.

UPDATE: Thanks to Greg for running his own test. iPhone 4S on Verizon, Dec-1-2011.:
