i use everytrail pro. i just copy a gpx from a website with the route (from bikely/garmin etc) then upload to my everytrail page then add it as a favourite on the phone,you can even load the map tiles at home on wifi so they are there on the phone when you have no 3g signal. i just use it as a failsafe so i can see if i have gone off route and how to get back.
will cane the battery on a 3g but isn't that bad on a 4. i tried runkeeper on the 3 but it was worse on the battery, not tried it on the 4.
