I had heard you want to create your own custom UI

I had heard you want to create your own custom UI for the Android and Iphone and such mobile devices. Instead of using the Built In GUI functions. If this is the case please share any good free tutorials on doing this thanks.

Yeah, the built-in GUI functions are rather horrible - in the Unity4 beta the GUI core has been rewritten so it should be faster/more memory efficient, but the Unity folks are still completely rewriting it from scratch for a post-4.0 release. What I would suggest is licensing an alternate GUI package, such as EZ-Gui or NGUI (my preference is NGUI).
