iPhone 4 units have started arriving at retailers ahead of the device’s June 24 launch. One such unit was photographed by a Walmart worker, showing off the phone’s new packaging. Unlike each past iPhone, the iPhone 4’s box does not feature a life-sized, forward-facing representation of the phone enclosed. Instead, it shows off only the top portion of the phone, facing the right, with its power and volume buttons, ring/silent switch, headphone port, auxiliary microphone, forward facing camera, and a portion of the display visible, all set against a black background. The sides and the top of the box, meanwhile, appear to be similar to past releases. A picture of the new 8GB iPhone 3GS packaging has also appeared online; it is identical to the past packaging apart from depicting a default iOS 4 installation instead of iPhone OS 3.
