For 4.99 (orig 10.99) you can get an app that silently runs in the background and sends your SMS messages to another number you choose. No traces it's there, no shortcut, no widget. Pretty funny, not worth the price in my eyes, but maybe for a wife who has a cheating husband. Pretty cool concept. Thought y'all might like to hear about it.
