We all know how secretive Apple is when it comes to new designs and concepts. It is really hard to say anything about what they might be coming up with or how would they make use of the recently acquired patent. However, a UK publication company; T3 has come up with a pretty neat concept video of what the iphone 6 might look like. However, the video is subject to ‘If’ Apple designs it according to their submission of new patent for the ‘wrap around-style display’.
Although there are many other conceptual designs of iphone 6 out there but we would say that the T3 design seems to be closest to reality. Guess we’ll find out who was the closest once Apple unveils the iphone 6. Check out the video:
