If your iphone is jailbroken you most likely already have sbsettings. If you do ( and i suggest you do its way more usefull than an app that simply hides other apps) you can hide as many icons as you want (even preinstalled apps ie weather, stocks etc.) it also allows you to turn your wifi or 3g off along with a brightness setting all from the home screen. The default activation is a swipe across the top of your screen from the carrier to the clock or so. Have fun!
