What's new with the iPhone 7? Either a lot and very little, depending on what matters to you in a phone.On the one hand, it's now imbued with far superior sonic performance, a much better camera and a more pleasant-to-use screen ? and now has no port to plug your headphones into.On the other hand, barring some slippage of the antenna bands on the rear of the phone, this looks remarkably similar to the iPhone 6 and 6S that preceded it.
