If you have an iPad or iPhone you probably have saved a web page to your home screen before if it's one you access a lot. Sometimes when you do this, for an icon you get a screen shot of the web page, and sometimes you get a cool icon or picture.
I wanted a cool icon!
Now if you save jasontoheal.com to your homescreen you get a nice looking icon instead of a screen shot. Thanks to Sam Dunn at Build Internet for the great tips. I found I needed a higher res though, but the iOS developer library was a big help.
