Apple and AT&T are working on a plan to tether the iPhone to your computer. All that means is the already stretched and overloaded AT&T 3G network will feel the strain, but at the same time be the route to doubling or even tripling capacity.
I've tethered my Nokia E71 and N95 using Joikuspot on AT&T's network with amazing results. Given Apples approach to simplicity this lifeline to the Internet will likely connect more people than ever before.
