IPhone/ Wyoming Maps w BLM overlay

Has anyone had any luck locating an Iphone app with the BLM Map overlay for Wyoming? I found one that required a CD to be purchased and then you could transfer it over- I am hoping to find one that i can simply download direct to the Iphone-

LAST EDITED ON Oct-12-12 AT 08:24PM (MST)[p]Download the Cabela's Recon Hunt app from iTunes. Has great topo maps. Plus, you can subscribe to get public/private overlays.

Another good map app is "Topo Maps." This one allows you to save topo maps onto your iPhone to use when you don't have a cell signal. Just keep in mind the GPS function on iPhone will drain your battery quick.

Hope that helps.
