According to Apple, the new iPhone 3G isn't supposed to start becoming available until July 11. That hasn't stopped a member of fan-site iPhonePortugal from getting his hands on a retail iPhone 3G package and posting pictures of the box and its contents.
The pictures are large and in focus, and they certainly appear real. The iPhone 3G sports the characteristic black plastic backplate, and a picture of the device in web browsing mode shows a little "3G" icon in the upper left corner, next to the signal strength indicator and the letters, "VF P"—presumably an abbreviation for Vodafone Portugal, Apple's iPhone 3G launch partner in that corner of the Iberian peninsula.
According to the forum member who posted the pictures, web browsing speed is "really good." However, the App Store isn't online, and Apple hasn't yet released a version of iTunes compatible with the device. (Thanks to Engadget for the tip.)
