When I tried Cellhunter (in early stage of its development), it didn't
feel so bullet-proof and stable, and I noticed I was collecting points
for invalid data which happened sometimes. And when moving, clicking
"update" constanly was giving me always 1 point more, and offline mode
wasn't so usable, so I had to colllect cells during GPRS connection,
which wasn't so stable these days. Maybe it changed now (well, i would
be supriced if it didn't :P), but openBmap client, data and website
just feel better, and most of important FSO and SHR devs are using
openBmap to collect cells - that's good enough recomendation to me ;)
