Removed the “iOS icons” <link>’s. Added a 152x152 pixel apple-touch-icon-precomposed.png into the root directory. (See http://mathiasbynens.be/notes/touch-icons#no-html or https://developer.apple.com/library/ios/documentation/AppleApplications/Reference/SafariWebContent/ConfiguringWebApplications/ConfiguringWebApplications.html for details). And just as a note: Apple.com is using this technique.
