Ok so I have a bball game i am making for the iPhone and I want the player to be able to customize their character. So I have a texture with multiple skins and jerseys. Am I able to move the uvs on the texture in game? And how is this done?

Yes. Via Mesh.uv

The Main page on the Mesh class, and the pages for the variables, have some good information about how to do it.
