LordTBT: one thing that you can do is hide certain elements using CSS to give mobile users a customized experience. For example, you can give certain tables or divs a class like "nomobile" (eg. ), and make that class hidden in MediaWiki:Wikiaphone.css.

You could use the same concept to create divs that are only shown to mobile users by creating something like a "mobileonly" class and hiding it in MediaWiki:Common.css (MediaWiki:Wikiaphone.css will be layered on top of MediaWiki:Common.css, so defining display:block in Wikiaphone.css will take prescedence over display:none in Common.css). All-in-all, it allows you to customize the mobile experience pretty significantly. Although it's a bit hackish, you could even use divs that are only shown on the mobile skin to create a completely different homepage for mobile users.
