So, other than a “lag fix” that both Samsung and independent developers are working on, the Sprint Samsung Epic 4G (a Galaxy S phone) is remarkably fast. (We’ll talk more about that in an upcoming article.)

How fast is it? In this video we look at a hacked Google Nexus One running a super-fast Froyo ROM with the stock Epic 4G. We look at overall interface elements (using the same Launcher app and similar widgets), side-by-side benchmarking, 802.11n data speeds, and 3G data speeds. Since the Nexus One doesn’t have 4G WiMax on-board this seemed a fair comparison.

I know, I know, you want to see how fast the Sprint 4G is when compared with the 3G on the Nexus One. For that you’ll have to wait for an upcoming video when I’m “on location” under a 4G bubble. Stay tuned!
