This brainy gathering of policy wonks, educators, content players and wireless providers will join forces to leverage mobile platforms for learning. (Did you know the number of mobile devices are expected to surpass the world population this year?) Attendees last year raved; check out last year's highlights here. We like the rather reasonable registration fees: $75 for educators and government folks; $100 for biz peeps. Even better: use the super-secret code: EDTECH50 and you can get a 50% reduction in the price!
