Janrain has recently released the second version (beta) of our iPhone library, Janrain Engage for iPhone, which includes a greatly simplified user authentication component, as well as an extremely simple social sharing interface.
To better test our library, we are hosting a Hackfest at our downtown office on Wednesday, October 27th from 6-9 PM. If you are interested in adding our library to your iPhone application, please come, and please bring your laptop. We will walk you through configuring your application with Janrain Engage and our 17+ providers (Facebook, Twitter, etc.), adding the library to your application, and the simple API calls. We will also provide pizza and beer, and we hope that you can provide meaningful feedback.
