Promote your business by creating a custom Bookmark icon for the iPhone. This is a great way for your customers to keep your website or blog close at hand with just a single tap on your custom icon.
Step 1: Create custom icons that are 57 pixels x 57 pixels and save them as PNG files. This custom icon can simply be a logo, image, or anything else that easily represents your company or website in a small area. Common programs that have the ability to save a file as a PNG file are Adobe Photoshop or Fireworks.
PLEASE NOTE: the resolution for your image should be no larger than 72 dpi.
Step 2: Rename the file to apple-touch-icon.png
Step 3: Upload the file to your root directory on your server. The root directory is where the files are stored directly under your domain, such as http://www.unitednotions.com/apple-touch-icon.png
That is it. Now on your iPhone, simply go to your website and download a bookmark to your iPhone.
HINT: There is no need to create the highlight or curved corners that you see on all the bookmarks on your iPhone. Apple takes care of this part for you.
