Apple's mystery N90AiPhone 4, its budget model, has been spotted after an inside look at Foxconn's new Brazilian factory. The look by a Gizmodo insider showed front panels for a device that looks just like the the existing model. As shown in a quality assurance sheet, the samples were part of a defective batch that was hurt by lensing issues, possibly either for the camera section or in the process of making the panel itself.
