Apple Theme Pack

Registers custom post types and custom fields for the Apple theme

Simply display a different theme to your <a href="http://www.apple.com/ios/" rel="nofollow ugc">Apple iOS</a> (iPod/iPhone/iPad) users.
Another plugin to check out is <a href="https://wordpress.org/extend/plugins/wptouch/" rel="ugc">WPtouch</a>; but depending on your needs, it may be overpowered.
This plugin becomes especially useful with WordPress-powered full-Flash websites. Since Apple has chosen to block Adobe Flash technology, your markets may require an HTML fallback.

iOS Alternate Theme

Automatically switch to an alternate theme for Apple iOS devices (iPod, iPhone, iPad).
