If you're headed to BlackBerry Jam Europe in Amsterdam, you'll likely want to go ahead and download the BlackBerry Jam Europe 2013 Mobile Guide to help you keep track of the things that are happening. With it you can view the full breakout session catalog, read up on speakers, view conference maps or create your schedule before getting to the event.
In addition to all of that, the conference app will automatically update when there are schedule changes, and synchronize with your conference calendar in the My Scheduler tool on your desktop. Just remember, the app is for attendees of the event. If you're not going, you can still download it but it will have limited function. Thanks, Dave!
