What's the difference between 3G and 4G?

Let's start out with the Gs. A G, in the phone world, isn't a gangster, it's a generation of mobile technology. 1G was the old analog phones. 2G was digital. Then it got complicated.

3G and 4G are both sorta high speed digital data networks. But there's no real standard defining what's called by which name. They were supposed to be a real break, with new, much faster technology coming for 4G, but the carriers really mucked that up with their marketing.
