Mapping app ios that displays map location and gpx waypoints

[+terratin]

I generally like waymarks, but it's too difficult to do anything with them when out and about with a phone. I've been looking at importing a gpx or google earth file into any suitable mapping software on my iphone, but basically failed. Cachly is supposed to have a function to load gpx via email. But my phone doesn't suggest cachly as one of the apps I can send data to for some reason. Pathfinder just brings you from waypoint to waypoint, and reading the gpx info is nearly impossible, and the map useless. Cachetur works kind of the same. Also a no. Any other ideas for this?
