iPhone Pro, an iPhone concept by Jinyoung Choi design studio, is designed for users who expect more from their mobile phones. With a 4.5 inch wide LCD screen and 2 side buttons, it offers the best usability possible. With a 1.2 megapixel 3D camera, it captures reality in a new way. It is designed in a manner that allows expanding its potential with ‘add-on’ devices. For instance, the addition of a DSLR lens enhances the quality of photographs. A beam projector, portable speaker, removable hard disk, or other devices can also be mounted onto the rear side of the phone.
