Following on the "TOPO Maps for MacENC and GPSNavX" thread, I noticed a new app just dropped that displays USGS topographic maps on the iPhone. They claim complete coverage of the USA, and, like iNavX, the maps are downloaded onto the phone for use when out of data service range. Although I haven't used it yet, it seems to have very limited quiver of actual nav tools. I am still waiting for a program with iNavX's function (or better yet, iNavX itself!) which supports USGS (or equivalent) topographic maps.

It is called TopoPointUSA and sells for $9.99. More info here: Link

Best regards,
