The top selling iPhone App right now makes fart noises. The lowest form of jokes takes over the iPhone. iFart Mobile selling for 99c stormed to the top of the paid iPhone Apps in less than 2 weeks.

The developer describes the iFart Mobile app with "iFart Mobile is a Digital Sound Machine and entertainment system which brings endless laughs and enjoyment to its users.

Combined with more usefulness and functionality than some other popular applications, iFart has a built-in security system designed to surprise and discourage iPhone theft, as well as a “Sneak Attack” function ideal for pulling pranks on parents, children, friends, teachers, workmates and employers alike." I assume there will be a lot of (hopefully simulated) farting under the Christmas tree today. Merry Christmas.
