GSM demo licenses in Germany?

Hi, As there are some German GSM experimenters here, what happened to your demo licenses after the DECT guard band frequencies had been auctioned away to AFAIR Vodafone? What a stupid idea, they did not listen to the technicians and just had the $$$ signs in their eyes :( I got a reminder last week, my license would expire soon, and if I would like to renew it. So I answered intentionally unknowingly "yes, please do so". Let's see what they will do now :) The second possibility would be asking the management of a German provider if they would lend me one of their unused guard channels. Although I see there chances I really would hate pulling this wire... Ralph.
