I'm at an airport right now waiting on my next flight. I have my iphone tethered to my computer and I was wondering something. I know that when I've tethered in the past I can look at the detail of my data usage and it's very easy to see when I tethered and when I didn't. If I stay under 5gb a month will AT&T look at the detail of my data usage? How often do the people here tether and have you had AT&T say anything?
