Well, at least not for me. Starting from the main page I see 7 links. 3 to
company websites, 1 email link, one to itself, one to google code and one to the
client downloads. So the two last ones could get more info. Clients does not
have any further infos regarding license or actual data. Same for the
code.google site. I really fail to find links to the sites you point out here.

Anyway, data can be found on the links you gave. Still I can't find a clear
license statement anywhere.

Don't get me wrong. This looks like the most promising db so far. I just like a
clear license on stuf I may use and contribute to.

We have the cell id in the GetStatus() / Status() method and signal combination:

Or is the cell tower id different from the cell id string? If yes and you need
more information exported let us know.

Yeah, we need to cover this as well. But before we do this we need to find out
why the GPS gets confused when uploading ephemeris. If this is fixed getting the
initial data from ublox as option is nice.
