Pop out to driving directions from your iPhone app

Had do to some discovery today on showing driving directions from inside an iPhone app. I've looked some of this stuff up before, and then didn't take good notes. So, here's my notes and a sample app that I used for testing.

Some good links:

• Apple URL Schema Reference
• Good question on StackOverflow
• Google Maps Parameters
• Handy trick for gettin Lat/Long coordinates from Google Maps

And the source for my test app is here.
