Looking for very simple apps

[+2tosail]

I'm looking for apps for iPhone/Android/Blackberry that will simply allow you to enter a lat/long, and use the phone's GPS to navigate to that point. It's for a local event, and I want to use it to introduce people to the concept of Geocaching without all the distractions of the full-fledged Geocaching apps, so the simpler the better. Anyone have any suggestions?

For Android, try GPS Compass. It is very simple, but does the job. On iOS, I have my kids use Commander Compass Lite. These two apps will let you enter coordinates, and give you an arrow to follow. Simple, which helps newbs understand a GPS better.
