The iPhone has a "fart" application...
there are all those useless apps like there is a zippo lighter app. You can flick you iPhone to light it just like you do in real life and you can even blow on the flame and it flicker "in the wind". Need a level? These's an app for that. Need a inclimeter? There's an app for that. want to play air hocky? Theres an app for that.
I got an "GPS" app which feeds off of the cell tower locations and can calculate where you are. Then it plots it on a google map. It was spot on when I was in Juneau but it only works good where Google has hi-res pictures. It would be an excellent tool for service calls if you do not want to invest in to real GPS navigation.
