I have a Droid incredible and use worksmart labs cardiotrainer. I use the free app, I've had it on for hikes, walks, snowboarding, and use it weekly for rides. It maps even when I'm out of cell range - the map itself doesn't show at the time I'm hiking, but the little blip that's me does, and as soon as it uploads the map appears. Keeps track of elevation change, average speed, max speed and charts it.
I can also upload my routes to mapmyride, which I do to be able to share with my group riders and for posting routes in advance. I just stick it in a shirt or jacket pocket.
I got DH a Garmin Forerunner 305 for his birthday and he loves it.
