Status of GSM base station positioning services & clients

[Risto H. Kurppa]

Hi there!

does anyone know what's the current status of GSM base station -based
positioning services..
How do the different databases compare to each other nowadays?

Are there clients to position the user based on the GSM base stations,
with on- or offline databases?
It'd be great to be able to detect the approximate location from GSM
signal and then hook up to GPS faster..


Thanks!
