Nokia have posted information about 4 game development webinars coming up and the full source code for the examples will be provided to all attendees :
Developing Games for Nokia’s New Symbian Devices with Symbian C++
31 May 9 am PST
Developing Games for Nokia’s New Symbian Devices with Qt
1 June 9 am PST
Developing a Casual Game with Qt Quick
2 June 9 am PST
Developing Games for Series 40 with Java™ Technology
15 June 9 am PST
You can get more information and register for these at https://www.forum.nokia.com/Library/Multimedia/Webinars.xhtml. Registration is free, and I expect (though really don’t know) you may be able to watch the recordings once they have been made, though you may not get access to all the source material if you watch it later.
Windows Phone developer contest
There is also a new Developer competition for Windows Phone. You can win a Samsung Focus. The rules are simple – create an app that is all your own work and get it uploaded (XDA Developers can help with this) to the App Hub.
