@gruber: If you think of it as a miracle that wireless networking works at all, AT&T is doing just fine.
Gawd, this made me lol. No, really. All my iPhone-loving buds curse AT&T while they simultaneously stroke their phones. Me included. If they think it’s painful now, wait until enough of the new iPhone users start making all those video calls. Can you say PAAAAAAAIN, PAAAAAAAIN? (if you thought of Spock and the Horta there, extra points.)
Being in IT and all, I know that for most of us there are certain machines that are the proverbial “Black Box” because they are not necessarily our area of focus. And really, shouldn’t wireless networking be one of them?
