One of the networks that I have been looking for on my trip around northern Europe is FON. Here, not far from Hackescher Hof, I found a FON location where I could get online with the Nokia N95 and make VoIP calls (using VoiceStick, my new favourite VoIP provider).
I’ll provide a more detailed update of my FON experience at the end of the trip, but I have seen FON APs in every city I’ve visited so far on this trip.
