Ok, downloaded the cellhunter database, this is what it stores:

provider	cell_mcc	cell_mnc	cell_la	cell_id	cell_arfcn	signal	gps_time	gps_lat	gps_long	gps_alt	gname	local_time	cell_type
IL ORANGE	425	1	3AFC	A2F9	92	19	1252151461	32.3668973	34.8627705	17.44	Baruch	1252185642	old_oldgps_near
IL ORANGE	425	1	3AFC	7D54	630	6	1252151461	32.3668973	34.8627705	17.44	Baruch	1252185370	old_oldgps_near
IL ORANGE	425	1	1D60	79CD	107	17	1252151461	32.3668973	34.8627705	17.44	Baruch	1252185368	new_gps

altitude is stored, good
speed missing, bad
hdop/vdop/pdop missing
heading missing (ok, I can't right now see how to use it but why not
to store it, it might become useful in the future..)
cell arfcn, no idea what's that..

So anyway also cellhunter could add some fields here and as it's on
Freerunner only, it shouldn't be too hard to also add the support to
the client.
