Field Test at 25c3

The 25c3 did not see much of a field test: OpenBSC was still in early development phase,
and we didn't even have voice calls working at the time.

However, we already received plenty of LOCATION UPDATING REQUEST messages from more than 1000 unique IMSIs, and we also
inquired the IMEI for each IMSI we saw.
