I use ALK CoPilot Live for a GPS app that has all the maps built into the phone and so works where there is no network, and I use MotionX GPS Drive if my entire trip will be in an area where I've got good cell coverage. Both are cheap and good. I've also heard good things about mapquest.
Bear in mind that the GPS receiver in any kind of phone is a lot less powerful than the receiver in a dedicated GPS unit, so the accuracy and position updating frequency are always going to be poorer with a phone.
