It can't be games or anything prank or anything that requires purchasing extra hardware. When I say wicked, I mean apps that do things you never would expect an Iphone to be capable of doing. Example of ones I find wicked are Shazam, Red laser, or Mocha VNC lite. Shazam falls in the category because before I learned about it, I thought only the human brain was capable of listening to songs and identifying them. Are there any other apps you know of that do things that are outrageously awesome?
