iPhone 4 3G Download Speed Twice as Fast as 3GS & Much Faster than iPad 3G

Daring Fireball’s John Gruber took a close look at 3G wireless data performance on the iPhone 4 as compared to an iPad 3G and iPhone 3G. His results? Quite surprising (to me) and in favor of the iPhone 4.

iPhone 4 3G Data Performance

Gruber measured 3G download speed, upload speed, and latency for the iPhone 4, iPhone 3GS, and iPad 3g. He also threw in data when holding an iPhone 4 in a way to create the left-antenna problem as well as the iPhone 4 on a WiFi connection.

The iPhone 4 topped all three measurements. I took his data and boiled it down to two numbers that interested me the most:

– iPhone 4 vs. iPad 3G download speed: iPhone 4 faster by 77.6%
– iPhone 4 vs. iPhone 3GS: iPhone 4 faster by 95%

I didn’t expect to see such dramatic differences in 3G download speed. This is especially true for the iPad 3G which is only a month “younger” than the iPhone 4.
