Comment 2 for bug 579469

I think we should delegate modifications to specialized softwares. (AndNav has too many options)

As a Vespucci developer (http://code.google.com/p/osmeditor4android/), I'm thinking about creating a "modify map" entry into OSN that launchs Vespucci on the corresponding area.
Vespucci is just an example and could be too complicated for beginners, but since we only call a map intent, we could choose any other (simple) mapping applications.
