IPhone 4 Dock

The Apple iPhone 4 Dock was released by Apple in June 2010 for the iPhone 4. It also supported the iPhone 4 S, which retained the same external form factor.

Description
The iPhone 4 Dock had a pass-through 30-pin dock connector on the back that allowed for charging and syncing over USB 2.0. A 3.5 mm line-out port could be connected to external speakers or an audio system. It also supported speakerphone calls. The docking cradle is shaped to accommodate the phone only and does not have room for an iPhone 4 Bumper. It includes no cables or power adapters. An alternative was to use the Apple Universal Dock with cradle inserts for the iPhone 4.
