At $15, the price is a little high, but starting tomorrow you can navigate the Metro system on your iPhone. The details of all the functions aren’t available on iTrans’ website just yet, but there are a couple pictures in the new iTunes app store (link requires iTunes) which seem to indicate it’ll be pulling train times from the published Metro schedule.
If they’re not using the Metro train-position API, one has to wonder why they bothered at all. Oh well.
At least it’ll get line service updates?
