Flexible iPhone
This concept is much closer to reality than you think. With the recent advancement of flexible touch screen technology, we are bound to experience this in the next few years. Samsung has been on the verge of this discovery with their AMOLED Display that was first showcased at the 2011 Consumer Electronic Show. The displays are bendable, can be rolled all the way up and can even withstand direct hits from a hammer. Massive screen sizes that are too big to fit in your pocket will be able to fold.
