How the get the 512x512 icon for an app.

Look for this app on the itunes.apple.com website (Google is your friend)

For example, this excellent app.

http://itunes.apple.com/au/app/bancomap/id309009025?mt=8

Look for the URL of the icon in the page (it's a 175x175 picture).
I use Safari, so right click on the icon and choose "Inspect Element"
