Sure, Apple claims the 3G is fast, but with all the problems with 3Gs connecting all over the world, just how fast is it really? The folks at Wired.com have decided to find out, and they need your help. They'd like you to test your iPhone at the TestmyiPhone.com network speed testing site, and then hit up their global ZeeMap to register your speed.
Instructions are over on their website, and they're testing both Edge and 3G upload and download speeds, so you'll have to run three tests total. You'll also have to sign up for a ZeeMap account.
The eventual payoff will be a relatively clear look at iPhone speeds around the world. Wired says that they'll eventually average global data, but there's a lot of things that could be done with data like this -- heatmaps? Speed per carrier? Once they get a good set of figures together, there's probably all kinds of things that can be done.
