Thanks for the info and sorry for posting in the wrong forum!

I have a no-service Iphone4 that I generally use with wifi. I have an android phone (using C:GEO) that I cache with but its also my main phone so when I go caching I just destroy my battery. My question is: Is there a way to preload map information on my iphone 4 for use with the geocaching app so I can use my iphone to cache instead of my android? Even if it was just for a small area that would be so much more useful than destroying my androids battery. Thanks for the help!
