Rear viewAccording to The Wall Street Journal, the iPhone is manufactured on contract in the Longhua, Shenzhen factory of the Taiwanese company Foxconn. Conditions for workers at the factory have been a matter of controversy.


Touchscreen
The 3.5 in liquid crystal display (320×480 px at 160 ppi) HVGA touchscreen topped with optical-quality, scratch-resistant glass is specifically created for use with a finger, or multiple fingers for multi-touch sensing. Because the screen is a capacitive touchscreen, no stylus is needed, nor can one be used. Bare skin is a requirement; users wearing gloves would have to remove them to use the touchpad, unless they are wearing electrically conductive gloves.

The user interface also features other visual effects, such as horizontally sliding sub-selections and co-selections from right and left, vertically sliding system menus from the bottom (e.g. favorites, keyboard), and menus and widgets that turn around to allow settings to be configured on their back sides.
