A website posted some photos of what would be the external frame - which is also the antenna - of the next generation of iPhone.
The information seems to be real since there was also youtube video that Apple had removed for violation of its rights.
There are very few differences, on the openings for the volume and ring/silent buttons, but also on the little notches for the antenna, which go from 3 to 4. This can seem trivial, but it appears that it could be solving the problem that was never admitted by Apple. We can view this in two ways: either there is a 3G antenna and a 4G antenna, or two doing both, which is the most likely solution because 3G and 4G can't be used at the same time by the firmware that chooses which gives the better signal strength.
Since the device has already been manufactured, at least for the prototypes, the upgrade should arrive soon. The only unknown information is whether this will be called iPhone 5 or iPhone 4 V2.
