Bug in iPhone 2.0.2 maps app.

I have run into this on several occasions.
Tap Maps.
Do a search (ex Pizza)
Select one of the results...
Tap "Directions to here"

Now, here is where I have had issues. If your Start point is not "Current location", which happens if you're rerouting in mid trip - when you select current location you cant click any route button: Heres how to recreate

Click the x to remove current start location, for example if its an old address.
Tap the directory icon on the right of the search field.
Tap Bookmarks.
Tap "Current Location"
Now you are back at maps with no way to click "Route"

You have to go back to Search and then back to "Directions" to bring up the keyboard again to do a search.
