Multiple “apple-touch-startup-image” resolutions for iOS web app (esp. for iPad)?

Question

I\'ve written an HTML5-based iOS web application and all seems to be working well, but I\'m trying to polish it up with multiple startup screens. The iPhone/iPod touch works

Answer 1

I just wanted to offer a combination of answers that actually worked. We found with the answer that was selected, the retina versions of the splash images were not being used. Pavel's answer fixed the retina version for the iPad. The following has been tested on iPhone (Retina and non-retina) and iPad (retina and non-retina).

I can't take credit for any of this, but this configuration works. Just copy and paste, make sure to make the images exactly the size dictated in their names.
