What size should apple-touch-icon.png be for iPad and iPhone?

Question

Are Apple touch icons bigger than 60x60 supported, and if so, what dimensions should I use for the iPad and iPhone?

Answer 1

With the iPad (3rd generation) there are now four icon sizes 57x57, 72x72, 114x114, 144x144.

Because retina icons are exactly double the size of the standard icons we really only need to make 2 icons: 114 x 114 and 144 x 144. By setting the retina sized icon to the corresponding standard icon iOS will scale them accordingly.
