Apple is reportedly in the early stages of development on two new (at least for Apple) technologies that could make their way into the iPhone in the next few years. 

The first is said to be a curved display, and according to a report from Bloomberg, this iPhone from the future would “curve inward gradually from top to bottom”. Based on this info, we picture the design resembling that of the LG G Flex 2, not the Samsung Galaxy S9, though we have doubts that Apple would opt for plastic build materials as LG did in early 2015.
