If you were at BlackBerry World™ or BlackBerry® 10 Jam last week, you might have seen the foursquare “Check-in Stations” we set up. Did you know they were NFC-enabled?

Four days prior to the two conferences, foursquare released an updated version of their BlackBerry® smartphone app. The biggest addition? Near Field Communications! You can now check in at a venue with nothing more than a wave of your NFC-capable BlackBerry smartphone. (Of course, the venue has to have NFC tags for you to tap your BlackBerry smartphone against. It’s not actually magic – it just seems that way.)

Peter Nofelt, Software Engineering Manager – BlackBerry at foursquare (you might recognize his name from BlackBerry DevCon 2010) shot a quick demonstration video of the onsite NFC experience with fellow BlackBerry platform developer at foursquare, Kyle Fowler.

We learned a lot about #TeamBlackBerry from your foursquare check-ins. At BlackBerry World, the Solutions Showcase had the most check-ins and was the most popular event, while the most popular session was a Hands-On Lab, “BlackBerry® Mobile Fusion Studio and BlackBerry Device Service,” whereattendees learned how to install BlackBerry Mobile Fusion Studio and BlackBerry Mobile Fusion for BlackBerry devices.

At BlackBerry 10 Jam, attendees checked in at the Jam Space most often. No surprise there – the Jam Space was where developers could “Ask The Experts”, port their apps to the BlackBerry platform (in minutes!) at the App Express station, or simply hang out with us at the Social Media Desk. The most popular conference session on foursquare was “Get Ready for Cascades™ Development,” where attendees got a preview of Cascades and the powerful tools behind it.

Of course, it wouldn’t be a BlackBerry conference if we didn’t have the swag to back it up. At the end of each conference, the five attendees with the most check-ins won exclusive foursquare “Mayor Badge” t-shirts. Check out one of the mayors of BlackBerry 10 Jam, Chad Tetreault — he’s the guy that brought you LensBoost, among many other apps.

Below are more of the photos you shared with us when you checked in on foursquare, including another picture of those awesome t-shirts! (I know, I want one too. That’s the problem with “exclusive.”)

Registration for BlackBerry® 10 Jam in Orlando is underway and we’re getting excited about all the speakers, sessions, and labs that you’ll be able to experience.  Did I say labs?  Yes, labs – and lots of them – run by our BlackBerry 10 development experts.  But for labs, you need tools, right?  You do. And we will have them. We will release the first beta of the BlackBerry ® 10 Developer Tools at BlackBerry 10 Jam! These toolsets will include:

• BlackBerry® 10 Native SDK
• BlackBerry® 10 WebWorks™ SDK
• BlackBerry® 10 SDK for Adobe® Air®
• BlackBerry® 10 SDK for Android™ apps

One of the best parts about BlackBerry 10 Jam will be the opportunity to have hands-on time with the tools and access to BlackBerry platform experts, who can help guide you, give tips and tricks and other info as you get started building apps for BlackBerry 10.

Not only will developer attendees get access to the BlackBerry 10 Developer Tools, but they’ll also be receiving a limited edition developer prototype device – the BlackBerry 10 Dev Alpha™.  This is not a BlackBerry 10 smartphone – it is a prototype running a modified version of the PlayBook OS which will help developers design their apps for the BlackBerry 10 smartphone form factor.  Just to be 100% clear – it’s not the final hardware or OS for BlackBerry 10 – it’s a device to help developers get started with designing for what’s coming.  BlackBerry 10 Dev Alpha is only for developers – not end users – and is only available to developer attendees at BlackBerry 10 Jam.

I also want to let you know now that space is limited at this show, so register sooner than later. We’ll have more information on the BlackBerry 10 Developer Tools as we get closer to the show – so keep checking back here to the Inside BlackBerry Developer’s Blog for more updates.
