Those who are obsessed with customizing their smartphone are going to be the ones most interested in the '4hone' concept phone. Philip Pearce has designed a phone that looks similar to a Blackberry, but is as customizable as an iPhone.

There is a mass market filled with iPhone accessories. Everything from speakers to camera lenses can be purchased to increase the functionality of Apple's smartphone. The 4hone concept phone integrates a few of the more popular accessories into its design. The phone features a removable translucent keyboard, a speaker with a Micro SD card slot and a camera. Smartphone accessories sell like hotcakes, so it's reasonable to believe that a smartphone that comes with a bunch of add-on accessories out of the box would do pretty good with consumers.
