I am developing for an AT&T phone made by Mitsubishi. It correctly formats and displays WML cards until I try to use input boxes or any other type of formatting/data controls. I can get things to work in the WinWAP WAP browser, but not on the actual phone. What am I missing here?
Your WinWAP browser probably interprets things differently than your actual phone. This is just one of the many problems that result from a lack of universal standardization in browsers and browser formats.
