We have put the images below for your viewing pleasure. Notes and a second picture after the jump. From left to right, iPhone 3G, 3Gs, and the purported 4G:
There has been some controversy if these are the actual 4G parts, which we will leave to you to draw your own conclusions on. If they are however, we are looking at a slighty longer phone with some sort of top reflective surface.
Feel free to hazard a guess in the comments about what it will do.
