I hope this helps you all out, and I expect to see you all making your icons so we don’t have those ugly screen shots on our iPhones!
Here it is in 4 easy steps!
Step 1: Open the image you want to use in photoshop or image editor
Step 2: Crop the image to 45×45 pixels.
Step 3: Save the image as a png file with the name: apple-touch-icon.png
Step 4: Save this png in your root directory of your site and you are done!
This is the finished product on my home screen!
