Dual Level Turns Your iPhone into a Digital Level

Phone/iPod touch only:

Free iPhone application Dual Level uses your iPhone or iPod touch's
accelerometer to turn your device into a dual-bubble level. That's
really all it does, and though it's a bit jumpy at times, it seems to
work pretty well.

Another thing I wish a BlackBerry could do!

iPhones, why are they are getting all the good stuff?

It makes a techie that doesn't have one want to cry.
