How do I set the icon that appears proper on the iPhone
for the websites I have created?
From the Apple Developer Connection Safari Web Content Guide for iPhone page Specifying a Webpage Icon for Web Clip...
The user can add a web application or webpage link to the Home screen. These links, represented by an icon, are called web clips. Follow these simple steps to specify an icon to represent your web application or webpage on iPhone.
To specify an icon for the entire website (every page on the website), place an icon file in PNG format in the root document folder called apple-touch-icon.png.
To specify an icon for a single webpage, or replace the website icon with a webpage-specific icon, add a link element to the webpage as in:
<link rel="apple-touch-icon" href="/custom_icon.png"/>
In the above example, replace custom_icon.png with your icon filename.
See "Create an Icon for Your Web Application or Webpage" in iPhone Human Interface Guidelines in iPhone Human Interface Guidelines for webpage icon metrics.
Note: The web clip feature is available in iPhone 1.1.3 and later.
I use RealFaviconGenerator to generate favicons and code for many browsers and platforms.
See the Specifying a Webpage Icon for Web Clip section of the Configuring Web Applications page of the Safari Web Content Guide in the Safari Reference Library.

You may want users to be able to add your web application or webpage link to the Home screen. These links, represented by an icon, are called Web Clips. Follow these simple steps to specify an icon to represent your web application or webpage on iOS.
To specify an icon for the entire website (every page on the website), place an icon file in PNG format in the root document folder called
apple-touch-icon.png
.To specify an icon for a single webpage or replace the website icon with a webpage-specific icon, add a link element to the webpage, as in:
<link rel="apple-touch-icon" href="/custom_icon.png"/>
In the above example, replacecustom_icon.png
with your icon filename.
Note: Safari on iOS 7 doesn’t add effects to icons. Older versions of Safari will not add effects for icon files named with the
-precomposed.png
suffix. See First Steps: Identifying Your App in iTunes Connect for details.
Add this in your head section:<link rel="icon" href="/your-icon-url"/>
