App Needed for iphone and others...

I'm looking to have an app built for the iphone and other smart phones that use apps. The concept is simple and fun. It's called, "isomewhereelse" It's for people who want to hide where they are from the people they love. The design would need to store backround noises that are all to be labeled appropriately. For example. 'busy restaurant", "concert"... Then when the person who's using the app wants to lie to somebody about where they are they can hit the background noise of their choise and have that play in the background when they make their call. So if the person is at a girl/boy friends house and wants to call their spouse, they can hit 'busy restaurant' and have that noise in the background of the call rather than a silent apratment....
