IPhone 4G concept in 5 colors plus motion-control? (Images)

The iPhone-4G will be awesome and could come in 5 colors plus motion-control. Right now it looks like that Apple won’t change much on the 4G design, which shall arrive earlier than expected (April). On the other hand this could be a good sign that Apple will make the new iPhone much more powerful (dual-core). Design is more expensive nowadays then technology.
