WPtouch
I have another blog that I use entirely for my own note-taking and reference, and I very frequently refer to my notes on my iPhone. Safari on the iPhone renders the pages wonderfully, but it is a bit of a pain to have to zoom in on the text of the page. This is when I realized an iPhone-optimized version of the blog would be so nifty.
WPtouch is the best solution for WordPress blogs. It’s as simple as a plugin installation, and it is very decently polished.
It renders in “mobile” mode only for iPhone/iPod/Android clients. It has an option for those clients to still view the site in “normal” mode. It uses JQuery for various AJAX and visual effects. It just works and looks good while doing it, and I’ve recently installed it on this blog as well.

I really like this wordpress theme you have. I can not find it at elegant directory though. Would you know where I could get it?

Dave, if you can’t find it at the author’s website, I’m not sure where it may be now… :-/

Hi - it’s a shame that my plugin was released after this post, I think I’ve created a mobile plugin for wordpress that kicks any others into touch (pun intended).
It’s called the Wapple Architect Mobile Plugin for Wordpress and it mobilizes your blog not only for high-end handsets like the iPhone and Android, but for every other phone in the world all the way back to old-school WML/CHTML phones.
One of its best features though is it’s ability to retain the style from web to mobile, so you give your visitors a consistent user experience. Instead of showing iPhone users an interface that looks nothing like the web site, a similar one is displayed.
The homepage is http://wordpress.org/extend/plugins/wapple-architect/ and it’d be great to hear any thoughts you might have on it! Get in touch if you need any help installing or configuring your blog!
