Here’s William from our BlackBerry Developer Relations team in EMEA to report on the most recent BlackBerry® 10 Jam tour stop! – Ed.

The London BlackBerry 10 Jam was our largest event to date, attracting developers looking to see what the BlackBerry 10 development tools are capable of. This was another great event to experience, as both the sheer number of developers and their positive attitudes alone were amazing. The venue, Vinopolis (a massive wine bar/conference center home-extension project bunker), was somewhat odd in its complex levels and floors and winding passages, but we didn’t lose one developer all day. They came, they saw, they enjoyed what they saw of BlackBerry 10 – now they want more!

Stephen Bates, Managing Director Europe, kicked off the proceedings with an excellent keynote job that covered all the points effortlessly and gave the day an energetic buzz that kept building after each presentation. Andy Tipton was our MC for the day and kept the flow going on schedule.

Vivek Bhardwaj presented a seamless “Experience of BlackBerry” presentation, generating ‘oohs’ and ‘aahs’ from the audience when they saw the demos of the photo correction app and new virtual keyboard UI. Michael Weitzel continued with an animated trek through the BlackBerry 10 architecture and was assisted by Luca Sale on the demo device showing Cascades™. Later, Nick Smith of Marmalade provided his magical demonstrations of games running on both a BlackBerry® PlayBook™ tablet and BlackBerry 10 Dev Alpha device.

Rana and Suavek both introduced what they were going to cover in the afternoon breakouts, and following their brief introductions we stopped for lunch and managed to move the almost 500 developers through the labyrinth to be fed and return for the lightning pitches.

The afternoon split into its native and web tracks, and we repeated the formula of Suavek being assisted by Nick from Marmalade. Yet again, this combination provided a lot of information and excitement. At the end of the day, we’d given out the BlackBerry 10 Dev Alpha prototype devices to a delighted audience of both new and established developers.This was another wildly successful day, and I was excited by the developer comments on Twitter®.

We generated a huge level of interest through this one-day event, but don’t take my word for it – take a look at what our developers are saying:

Yesterday's WebWorks session at #BB10Jam was awesome and even got my 14 year old inspired to create apps. @BlackBerryDev—
