A wholesaler website has leaked what appears to be real parts of the next iPhone online. Whether this is by accident or not, well, we don't know. The site does claim to have gotten the parts straight from the original factory though. They also have pictures comparing the parts of the iPhone 3G to the next iPhone, though this are really the internals that may or may not help with folks trying to guess the new specs. The bad news though is that the next-gen iPhone will not have a OLED screen - it's still LCD.
gizmodo.com - It looks like the web site and the new parts are legit, but who knows. They also sell every single spare iPhone 3G part you can imagine—as well as original factory parts for Blackberry, Nokia, LG, HTC, MacBooks, and even Nintendo. They claim the new iPhone 3G 2009 parts will ship "within 5 to 12 working days.
