It seems like there is enough smoke in the air to think the hypothetical dual-camera system in the iPhone 7 plus may be a real thing. Most recently Mac Rumors released drawings from an alleged Apple casing subcontractor.  If true, the 5.5 inch phone is getting a dual-lens camera system.

This could mean that the camera in the iPhone 7 Plus is significantly better than the camera in the iPhone 7. It looks like the iPhone 7 Plus may also exclusively get a smart connector. 

If the rumors are true and they end up removing the headphone jacks and increasing the disparity between the normal and plus sized iPhones, people are going to go nuts when they announce these in September. Buckle in.
