Just got back from my trip to Germany. As recommended on this forum, I got a Fonic SIM card at Lidl, which worked out great. If I remember correctly, it cost something like 9 Euro and had ~6 Euro of starter credit on it, which is a pretty sweet deal. I also bought a 20 Euro top up card to bring the total to 26 Euro, which turned out to be far more than I needed. After 12 days of somewhat heavy data usage (using Google Maps, checking email, looking up train schedules with the nice ZugInfo iPhone app, browsing the web a bit) and a little bit of phone usage (a few calls within Germany and a few to the US), I still had 13 Euros of credit left. I had decent connectivity all over (I was in Berlin, Potsdam, Dresden, St. Goar, Bacharach and a few other places) with 3G service in the larger cities and Edge connectivity elsewhere. The only difficulty was activation, which was a bit confusing with my crappy understanding of German, but once I got it figured out, it was smooth sailing from there.
Thanks for the help folks
