Use iPhone to find parked car, campsite, etc
I was browsin' the App Store with my new 3G S (actually, I was using my computer, I hate the mobile App Store) and was wondering if any of you could help me find an app from personal experiance.
I want an app that allows you to mark your current location, then get directions back to that spot later, like finding a trailhead or parking spot. I was looking at G-Park, but it seems like that just drops a pin in Maps.app. I was thinking of something that, say gave you a direction arrow and a distance, like my old Garmin.
Incedentally, do any of you know if the built in compass in the 3G S is a public API, or just in-house?
