Right now, I have the build in map application that comes with the N810, Maemo Mapper, and QTmapper (like maemo mapper but less popular). I was wondering if I would be able to delete the original N810 map and still be able to use maemo mapper. I wanted to free up some memory and that seems like the most obvious place to look.

Also, If I ever want to get the map back, would I be able to download it again?
