Did You Know? (TM) You can use your G1 as a metal detector?

It’s true! The built-in compass can be used as a metal detector, allowing you to detect keys that are very close to the phone. Is this particularly useful? Probably not, but now you can rub your phone against people like a stud finder and perhaps make new friends when you search for their “keys.”

Some folks at HDblog.it shot some video of the app in action. Worth a look.
