Monday (that is tomorrow!) it’s time again for the Frankfurt CocoaHeads meeting.

This time we plan on having some hands-on iPhone sessions. In the spirit of NSCoder Nights please bring your code and projects. We will try to work together through some of the problems. And we will also celebrate the lifting of the NDA with some beers.
