Even if Foxconn employees would not know much about the new iPhone 5, we learn from 9to5mac that Apple is already testing prototypes of the new terminal and they would come with 1 GB of RAM, just like the iPad 3. The terminals would have the new hardware included in the iPhone 4/4S cases and use a similar version of the A5X chip, and this explains the existing of 1 GB of RAM. The A5X chip was built especially for the iPad 3 because it has a quad-core graphics chip, but the new iPhone does not need such a thing, so either it will bring the same processor but more RAM or it will have a different processor but still with more RAM. Even if Apple is testing prototypes in iPhone 4S cases, it seems that the device will have a new design, but the company does not want it to appear on the Internet, so we will probably only see what it looks like in the weeks before the launch.
As for the new iPod Touch, it is present in iOS 5.1 under the name iPod 5.1 and unfortunately nothing is known about it apart from the entry from the new version of the operating system. Returning to the iPhone, it was almost logical to double the available RAM memory because the iPad 3 has it and Apple usually implements the new hardware in the iPhone terminal as well. It would not be excluded that the processor in the new device is also A5X considering that Apple simply reuses the processors from the iPad in the iPhone and I think that we will see the quad-core processor in iDevices only next year.
