Are you getting enough out of iPhone Map.app?

It may have more features than you realize:

iPhone and Google Maps: Go to here -- just drop the freakin' pin ...

.... Today, when I was switching from Map to List view, the "Drop Pin" button caught my eye. I'd ignored it for a while. What the heck did it do, anyway?

Riiiggght. It drops a pin on the map. It seems to leave it there, after the first time I did this the button changed to "Replace Pin". I didn't see a way to "Undrop Pin" -- maybe once you put it on any map it's bound to a map forever.

You can move the Pin around, bookmark it, get directions to it, etc...

We need product documentation like "Power User tips and things longtime users tend to miss".
