Try MotionX GPS. Predownload the topo maps before you leave home (free). The app can also broadcast your position/updates to a distro list once it touches a cell tower. Not a bad idea if you're flying solo. Many other intuitive functions embedded as well. I think the pay version is about $6-7. Well worth very cent.
PM me if you have any questions otherwise just hit up the App Store. IMO, it's one of the best out there.
(I should probably clarify this- Using your iPhone assumes you have a pretty good understanding already of tracks vs routes, gdb vs gpx, how to combine multiple tracks into one using Basecamp, etc. If you know this, use the iPhone. If you don't, you'll be overwhelmed quickly.)
