I need an idea over mobile application. Once the idea is selected i will select for developer. It can be utility , entertainment, game(less preferred),Internet application or any thing you think is creative and unique. Example Fring , qik ,some calculator, locker application, these are already built i am looking for something unique. I will reward the best advisor. and will give a chance to develop it.(optional only if you want) If you do good, we are gonna work on more upcoming projects. Scott
