What are the dimensions, file types, and ppi of an iPhone icon?
<p>What are the specifications for the icons required by Apple for a custom iPhone application published?</p>

<blockquote>
  <p>57x57, PNG, No Transparency, No Layers, 72 PPI</p>
  
  <p>512x512, TIFF or JPEG, No Transparency, No Layers, 72 PPI</p>
</blockquote>

<p>Note: iPhone OS applies rounded corners, optionally shine, and other effects</p>

<p>Also have a large version of your logo with the name of the application in case Apple contacts you needing a version for marketing purposes.</p>
