While the $10,000 is a pretty good incentive, the winner will be able to hear his/her composition on 100 million handsets and it will also be made available from the Ovi Store. To enter the contest, head over to the sourcelink. If it helps, Nokia says it is looking for a ring tone that is "fresh, expressive, original, creative yet distinctively a Nokia Tune." And if you don't get the grand prize, you might still end up with one of five runner-up prizes of $1,000. Now get to work!
