We talk a lot about 3G networks here on CrunchGear, but for a good percentage of the country, it’s moot. 3G is still hard to find oudside of high-capacity metro areas. AT&T, though, is changing that, as its plan for 2008 is to cover the top 350 leading US markets. What’s more, it says that its 3G layout will also include the foundations for a 4G network, which will be layed out at some point in the future.

That’s good news for AT&T, and good news for our readers who aren’t in the big, bad cities.
