I just installed a really nifty WordPress plugin called WPtouch. If you are reading this on a normal PC, Mac, or Linux browser or even an iPad, you won’t see any difference. If, however, you look at the site on an iPhone or other smartphone, you’ll see a friendly mobile interface that takes less time to download and looks like a mobile App. Of course, you can switch back to the normal view at the bottom of the page.
If you run a WordPress site, give WPtouch a shot. It does exactly what it says it will do.
