While we still wait for the new mapsforge vector map library, I got a nice looking hires map on my galaxy note by using the tiles from cloudmade. They have extra tiles for hires displays.

You can use any map style from http://maps.cloudmade.com/ (http://maps.cloudmade.com/).
I made a second map for bicycle in night which looks fine on amoled (better than the nightmode in locus)

I don't know the regulations for tile downloading on cloudmade, so use with care. I used the slowest setting in mobac.
If you don't need it now, you can wait for the new vector library with better resolution handling and custom map styles...
