Would you like to add a little more functionality to your iPhone's Spotlight? SpotURL is a new jailbreak tweak, by Filippo Bigarella, that allows you to visit a website straight from the Spotlight page.
Instead of having to enter a web address in Mobile Safari, SpotURL will let you enter the address right on your iPhone's homescreen. For quick navigation to a web page, SpotURL is about as good as it gets.
