Supernova in San Francisco and Techcrunch are looking for the next great mobile ideas...
"There are plenty of mobile devices and services, but the possibilities are even
greater. For Mobile Connections at Supernova 2008, we're looking for game-changing innovations that provide a glimpse of the wireless future. This is not a startup contest -- it's a search for ideas. We're challenging anyone to make submissions... but, please, NO commercially-available products/services. We DO want to hear about innovative concepts, prototypes, research lab projects, hacks, and business ideas. If your submission blows us away, we'll invite you to showcase it at Supernova 2008. You'll also enjoy coverage on TechCrunch -- the leading media site covering emerging technologies and companies today; and the Supernova Conversation Hub. There will be no charge for those selected."
Seems like a good opportunity to me as the usual entry fee to the conference is $1695. The closing date is 23rd May 2008 and you can find out more on their website. Good luck!
