An employee of Pegatron — one of the various manufacturers Apple employs to actually create their products — posted the above photo to here Weibo profile. The image has since been removed, but not before various websites pulled the photo.
The picture shows dozens of devices in diagnostic mode, which makes sense: the employee was apparently in the quality assurance department, and these devices are being tested before being packaged for shipment.
The iPhone 5C is expected to be available shortly after the rumored September 10th event. The device is also expected to be Apple’s colorful, lower-cost product.
