According to various sources if you add a png file named apple-touch-icon in the html root, the iphone use it as icon for "add to home screen".
I tried to add it to local /web folder, also tried to add a specific header section (<link rel="apple-touch-icon" href="apple-touch-icon.png" />) in plugins/tersus.appserver_1.3.43/DefaultWebapp/iphone.html but nothing works so far.
It raised a few questions:
how to modify header section localy or globaly? Not just add but modify existing info.
where's the project root? /web?
did you sucessfuly added apple-touch-ico.png?
I'm on Mac 10.4.11 with bundled studio and server.
For best results, use the Firefox browser..
