Visiting site with iPhone or iPod touch causes default theme to switch to iPhone theme

The idrupal_init() function is incorrect in this module - it changes the default theme site-wide instead of changing the theme for a particular user.

See the following code for comparison:

    // Set to our iphone theme - commented out b/c we need to set as $custom_theme
    // $conf['theme_default'] = IDRUPAL_THEME;
   // Override custom theme setting.
   $custom_theme = IDRUPAL_THEME;
