Hello all, I'm going to be giving a presentation about free software GSM implementations at the FSFE's Berlin meeting on December 9th, 2010. It will be very elementary and newcomer-friendly. I'm planning to go over OsmocomBB, OpenBTS and OpenBSC, and discuss their security and practical implications. The talk will start at 19:30 in Newthinking Store Tucholskystr. 48, 10117 Berlin. You can find more about it on http://aligunduz.org/blog/free_gsm_talk_next_week.html Considering I'm not an expert on GSM myself, it would be nice to have people more familiar with it in attendance.
