You can make a shortcut directly to a web page on the Home screen of your iPhone 3G. These are called Web Clips. To make one, follow these steps:

1. While on the site you wish to make a Web Clip for, press the + icon at the bottom of the screen.

2. Tap the Add to Home Screen.

3. Edit the name of the clip.

4. Tap Add.

If you grow tired of the Web Clip, there is a way to delete it as well.
