RIM mentioned at BlackBerry World that they have a whole new BlackBerry Jam Sessions idea for Hackathons and it looks like they are starting to roll out. They announced on the DevBlog that the first BlackBerry Jam Sessions hackathon happened in Recife, Brasil on August 25th with 80 developers creating apps. They have announced 14 more BlackBerry Jam Sessions that will be happening in LATAM from now until November with registration opening 20 days before and the cost being free.
I highly recommend keeping an eye out on www.blackberryjamsessions.com for he schedule where you can register. Let us know if you go to any of the Hackathons!
