Why won't this stupid app work!?!?

i will probably sound like a perv throughout this question but i don't care. i have downloaded an app called nude it this app allows your ipod or iphone to see poeple without their clothes. i have downkloaded it and jailbroke my iphone 3 but whenever i try to put it on the iphone it say "the app "nude it" was not installed on the iphone because an unknown error ocurred (0xE8008001)." any idea what the problem is?
