That was a bit unexpected. RIM has been pushing hard to sign up developers for BlackBerry DevCon Europe in Amsterdam from February 7-8th. They have been offering aggressive discounts and incentives but I was surprised when JoDo let me know that is is now SOLD OUT! RIM confirmed as much on their DevCon Website saying that registration is now closed. As far as I know the capacity was 1,000 developers (at least according to the sponsor prospectus PDF) which is a nice following for RIM.
Let us know if you will be going to DevCon Europe!
