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.

In this version, we have streamlined authentication and added very easy-to-use social sharing. By using this library in your iPhone application, you can quickly authenticate your users on a number of existing providers (such as Google, Facebook, Yahoo!, etc.) and allow them to post status updates on Facebook, Twitter, MySpace, LinkedIn, and Yahoo! all through one screen, by configuring only one API call. This can be done in as little as two lines of code!

Again, we are really interested in getting your feedback, and we hope that you can come. If you are interested in attending, please RSVP to iphone-dev@janrain.com no later than Monday, October 25th. We will be limiting the number of space to about 20 developers.
