The latest of these images come from italian site SpazioCellulare, and they look very convincing. The images appear to reflect many circulating rumors but as such it maybe a very good mockup.

There appears to be an extra button on the lower-side of the case, perhaps a camera button and shutter button? The headphone jack for the iPhone appears to have moved down to the bottom of the unit. It also doesn’t seem to have the roundness that the iPhone 3G has. With any rumor, we aren’t confident that these images are 100% legit but they serve as interesting speculation.

There’s only about 3 days till WWDC on June 8th, stay tuned!
