title: How to handle hi res and low res of application's Icon.png for iPhone and iPhone4
body: <p>I have already provided both Icon.png (for iPhone) and Icon@2X.png (for iPhone4). 
  The thing is, when I just provided Icon.png of size 144x144, the console outputs this message:</p>
  
  <p>"iPhone/iPod Touch: Icon.png: icon dimensions (144 x 144) don't meet the size requirements. The icon file must be 57x57 pixels, in .png format (-19014)" </p>
  
  <p>But this renders icon in both iPhone and iPhone4 well.</p>
  
  <p>I want to be able to remove this issue so I reduced the size for Icon.png to 57x57 and created Icon@2X.png with size 144x144. After this, icon for iPhone seems fine but iPhone4 uses Icon.png and the icon renders a low res image.</p>
  
  <p>Any suggestions?
  Thanks!</p>
