Forbes reports a leak that a cheaper iPhone will be coming to the market. The budget iPhone concept will consist of a colored plastic casing. Does this sound familiar? Remember the iMac desktop? The plastic colored stationary computers? It looks like we might be going back in time with this one. Consumers expect the budget iPhone to be pieces of repurposed iPhone 4s' that will create a plastic backing. They also hope that the budget iPhone will sell for less than $250.
