I'm developing a website that needs to be compatible for mobile phones (esp. BlackBerry). How can I debug it's CSS? I already installed the Default User Agent plug-in for Firefox problem is I just don't know how to add the BlackBerry agent.
Next problem is how can I properly emulate the mobile site? without the actually having the device.
I'm using Windows 7, Firefox + Firebug + Web Developer Toolbar. I know XHTML, CSS and WordPress.
