I understand that I can link my iphone with my iMac Intel Core Duo Wi-Fi (via Airport?) so that I can get faster iphone speeds at home. A client of mine tried to explain how I could do this, but when I tried to set it up at home, I just got lost and couldn't get it to work. I need someone with patience to explain step-by-step just how to do this. I am too new to Mac to understand the function of the various settings on Airport and my iphone 3G, so that I can do this on my own. I spent a whole evening struggling with this, looking through the iphone User's Guide and trying things. I couldn't seem to find what I was looking for. What I was able to find didn't seem to give me enough info to set everything up. Then I started thinking that maybe what I was trying to do wasn't even possible using only the iMac. Whoever takes this on, my thanks to you in advance!
