I'm not sure what he's talking about. I don't mean for that to sound snarky. I just feel like I'm being yelled at when I honestly don't know what I did wrong. When I start building a web app I start with standards, assuming that my early adopters will likely be using Safari, Firefox or Chrome. Mobile Safari usually Just Works(tm). Is he talking about custom iPhone stylesheets or what?
