I need 3 programs. They all do the same but i need them for facebook, iphone and android.

What the program needs to be able to do, I will not give the full description until I have hired someone.
The program needs to be able to upload video/photo from phone/computer and post it to your friends on facebook, they then need to be able to upload a video/photo back to you and all of these actions should appear on your facebook wall.
There should be a special app on the mobile devises to do this but a special application inbuilt to facebook to do this in your computer.

This is the first part of the project, there are few things I am not telling about but they are minor.
