Yep, the is finally quite good and you have quite a lot of data to work with, just for example, the planet file, that has ALL data from the OpenStreetMap project, has:
  • 21 GB in compressed PBF format
  • 45 in uncompressed PBF
  • about 400 GB in uncompressed XML
Of course you can also just download the much smaller regional extracts and work with that.

There are already multiple OSM routing projects, check out the routing wiki page for comprehensive summary.

I'm working on it - checkout the modRana project. It already works on Fremantle, Harmattan, Android, BB10 and other platforms and I will also support Sailfish soon.
ModRana also already supports offline routing (with spoken turn-by-turn directions) using Monav and processed OSM data.
