The concept phone pictured above is a designers dream, Antoine Brieux, of the new Liquid Metal iPhone 5. This French designer wrapped the new iPhone 5 concept in a high performance Liquid Metal alloy. The home button on the front of the phone is a "virtual" button and sits in the same place as the older iPhone's. The LCD screen is 4.5-inches and due to the virtual button this widescreen could potentially do 16:9 ratio.
Only time will tell if this concept iPhone 5 will be close to what Apple will actually put out later this year, but it looks cool and stokes the fire a bit.
