One Apple iPhone owner has posted to YouTube a video shootout that pits an iPhone running on a 2.5G EDGE network against one rigged with 3G HSDPA access in a simulated speed test.
The mock 3G iPhone was connected via WiFi to an iMac whose internet connection was supplied with a HSDPA modem and then shared, while the traditional 2.5G iPhone was run on a standard overseas EDGE wireless network.
Based on the test results, which are largely theoretical given fluctuations in mobile wireless speeds from region to region and provider to provider, the 3G iPhone loaded the same web page as the 2.5G iPhone in nearly half the time.
