2G, 3G, 4G, and everything in between: an Engadget wireless primer
It's hard to believe nowadays, but in a simpler time, cellphones really were called "cell phones," not dumbphones, smartphones, feature phones, or superphones. They bulged in your pocket -- if they fit in your pocket at all, that is -- and they made calls. That's it.
