Why does an iOS Universal build give this error?

Why does an iOS Universal build give this error?:

"warning: iPad: Icon.png: icon dimensions (57 x 57) don't meet the size requirements. The icon file must be 72x72 pixels, in .png format (-19014)"

I tried building with icon.png sized at 57x57 and got this error. I resized icon.png to 72x72 and I STILL get this error.

I even tried with a 57x57 icon.png AND a 72x72 icon@2x.png BUT I still get this error.

What am I doing wrong?

I think (someone correct me if I'm wrong) that you need the ipad 72x72 to be called icon-72.png. icon@2x.png will be 114x114 and icon.png is the 57x57.

hope this helps.
