If you do browse this site with your computer, chances are you didn’t notice anything. On the contrary, if you browse it with a mobile device (an iPhone for example), it’s kind like a new user experience!
In fact, in almost 1 minute, I made this site adapted to mobile browsing. How? Just used my friend Google who found WPTouch, a WordPress plugin which in fact behaves like a configurable theme, but only on mobiles.
WPTouch features are impressive (and free). Most notably, supported user-agents include: Android, BlackBerry9500, BlackBerry9530, CUPCAKE, dream, iPhone, iPod, incognito, webOS, webmate.
If you own a WordPress blog and want to offer to users the best user experience, I would recommend using this plugin.
