Symbian Partner Network members may apply, via the website, for space in the exhibition part of the event, free of charge.
For the first time the Symbian Partner Event (SPE) opens its doors not only to Symbian partners, but also to mobile developers, handset manufacturers, network operators, the Open Source Community and members of the press. Whether you are new to mobile or an experienced Symbian developer, SPE has something for everyone.
Details on the San Francisco event can be found here. There is also a recap of the London event from April this year on the site as well.
