A question for all you techy cachers.......

a caching team I know has just got an Oregon 300. Now, as I only have an old eTrex Legend, I don't really know what the 300 can do. He has a caching app on his iPhone that will show nearest caches, and descriptions etc.......I assume that's from GC.com, just like looking on't t'interweb? Now, the big question is, can the 300 do that? i don't think it will, but hey, what do I know?

They are not premium members, either (neither am I)

Any help, muchly appreciated!
