What are the correct pixel dimensions for an apple-touch-icon?

Question

I\'m not sure what the correct size should be.

Many sites seem to repeat that the apple-touch-icon should be 57x57 pixels but cite a broken link as their source.

Answer 1

It seems that Apple guidelines as of August 3, 2010 now include the "High resolution" images (for iPhone 4) in their "required" icon sizes.

Looks like we need to provide both a 57x57 and a 114x114 image now, as well as a 640x960 title image.

See Custom Icon and Image Creation Guidelines (Javascript required) which is part of a whole document:
