If you aren't a Safari user, you may not know the joy that is the home screen. Safari gives you a preview of your 12 most frequented sites when you open a new tab. It's a great tool when you want to check your Twitter account, but don't want to bother typing in the address. Giving you a taste of this brilliance is Fav4, which lets you choose your top four favorite sites from an available list and, set that as your home screen. It's quite attractive, and easy to edit if you change your mind — just click on the settings wheel at the bottom right of the screen. Plus, if you don't see one of your favorites on the list, you can just drop them a note!
