OpenSignalMaps? OpenBmap? Cellhunter? OpenCellID?

If you've got an android device, OpenSignalMaps and OpenBmap have clients to monitor wifi/cell towers although I prefer OpenBmap for making their data available for download again ("open"SignalMaps just makes maps for website/client).

Hey Maxious - I'm one of the opensignalmaps guys. We're working on opening up our data, we're just trying to figure out the best way to go about it.
