Installed this: WPtouch: Mobile Plugin + Theme for WordPress from BraveNewCode.
Tried to test it with testiphone.com but they are not sending the right agent string. This site however is cool – it will create iPhone-y icons. Heh – iPhoney… someone should register that….
So, tested with Firefox and the about:config trick described here. Be sure to blank out any other *.useragent.* strings you find in their as well, which definitely voids all warranties.
Anyone with a real iPhone care to tell me how it looks?
