I think you can get alot of experience by doing it yourself, there are alot of very interesting problems to solve to get a good mobile editor. If you just choose a small problem to solve you can probably make a very nice editor pretty fast.
There are editors running on mobileplatforms, Josm works on the Nokia I’ve heard (albeit very slowly), you have Python for the S60 phones, and perhaps Merkaator which might be compilable for Nokia 800 it’s QT so I don’t know…
