Simple mobile skin auto change/lv

The following code snippet (added to LocalSettings.php) allows for detection of an iPhone, followed by automatic switching of the skin / theme to an iPhone-compatible one (in this case, WPtouch). Add this code to your file (replacing the current  variable) after installing the iPhone-compatible skin. This will make the default skin "wptouch" if an iPhone, "vector" otherwise. Modify as needed. If file cache is enabled you may need to disable it to prevent visitors from seeing the wrong skin.
