My idea was just used by Nokia without giving me any award

About 9 months ago NOKIA launched a campaign for everyone... If anyone have any new idea to improve their new cell phones, he may submit and receive part of their profits... So i created an account and submitted my idea... which they refused and informed me that they will not use it. And this month Nokia launched a new phone containing every detail my submitted idea contains without my knowledge and without giving me any appreciation. I am a Lebanese citizen and I still own the account on their website containing my submitted idea details and date. I want to know if I can sue Nokia for steeling my idea and using it in their new phone. i am ready to pay anything if it is a good idea to sue them... Thank You Georgio Daher
