We step into the world of the iPhone Concept today with two videos which have popped up on YouTube. The first video shows quite a few neat looking iPhone 4G concept designs, the one I liked the most was the transparent version.

The second video seems at first judging by the time length to be quite a bit longer than the first, and covers even more iPhone 4G concepts; however the concepts only last the first 55 seconds and the rest is just music.

Personally these concepts show us what Apple could do with the iPhone design, and what could come in the iPhone range in future generations. I think the iPhone still has a lot more to give in the coming years, don’t you?
