Nokia and Windows Phone Geek come together to bring you the Lumia Geek 8-Week Challenge!

They simply want you to show your best, coolest Windows Phone 7.5 and 8 apps between now and 8 January 2013, and you could win some big prizes, including a free trip and passes to Mobile World Congress 2013 in Barcelona, an App Demo in the WIP Jam at Mobile World Congress, customized Nokia gear, and much more. 

Here’s the deal: You make the apps, put them in the Windows Phone Store, and then enter them in the contest.

Now is the time to start. You have less than four weeks to show Windows Phone and Nokia your greatest Windows Phone apps.

So get over to Windows Phone Geek now!
