An iPod with a touch screen feature. Visually similar to the iPhone except for:
The absence of the phone speaker above the screen.
The location of the earphone jack, which has always been at the bottom. The iPhone's, up until 4S, was at the top to accommodate the 30-pin connector slot, phone mouthpiece hole, and external speakers at the bottom. On the iPhone 5 and 6 lines, the size of the Lightning connector slot enabled the placement of the earphone jack at the bottom. The earphone jack is absent from the iPhone 7, instead included separately as a connector via the Lighting port.
Size, with the introduction of the larger iPhone 6 line.
