Somehow unsurprisingly, they are all concerned with the design of the antenna, since it's all but certain that Apple is not particularly eager to go through the infamous "Antennagate" scandal once more. As you most probably remember, "Antennagate" stands for the signal strength drop that many iPhone 4 users experienced when the handset was originally released.
These design changes may very well be there to prevent something similar from happening with the Verizon iPhone, so let's take a closer look at them. As you can see from the first picture below, one more black band is added on the left side of the new iPhone compared to AT&T's version of the handset, and its vibrate switch, as well as the volume rocker are slightly lower. There are no differences on the bottom side, while, on the right side, the presumed Verizon iPhone has one more black band. It's worth mentioning that on these pictures the SIM slot is still there, which gives us hope that LTE support may be added to the Verizon iPhone. The last difference is that the black band on the top side of the AT&T iPhone is not there any more.
Apple is known as a company that strives for perfection (Steve Jobs is certainly (in)famous for that), and the "Antennagate", which was recently given the award "number one tech-fail of 2010" by CNN, left a stain on the Cupertino-based company's reputation. These images, if genuine, give us an idea where the iPhone is heading design-wise. And who knows, if this is not the Verizon iPhone, these may very well be the first iPhone 5 pictures! Of course, we shouldn't underestimate the possibility that this is nothing more than a hoax, so we don't plan to get too excited for now.
