A firm called GlobalDirectParts claims to have the parts of the next generation iPhone. They have uploaded a detailed video showcasing the parts of the next iPhone, which they are referring in the video as the iPhone 5.
We get a crystal clear look at the charging-port flex-cable and outer aluminum skeleton of the device. There are several key differences between the iPhone 4 parts and the new parts we are being shown — displayed side by side in the video — including the absence of several of the black, plastic strips on the casing. This new iPhone shell still has a micro-SIM card slot, which could mean several things: it belongs to a global CDMA iPhone, it is a slight retooling of the current GSM iPhone 4 (iPhone 4GS anyone?)
Anyway, it's expected to see and hear about such rumors, I can't confirm whether it's fake or real parts, while they are still not confirmed officially from Apple.
