Is a 'foldable' iPhone in your future?

A flip phone may be coming back. According to Bank of America Merrill Lynch, by 2020 Apple hopes to come out with a foldable iPhone “that potentially could double up as a tablet,” CNBC reports. An analyst made the news in a note to clients Friday after meeting with several Apple suppliers in Asia. Lenovo and Samsung have also looked at concepts for devices with foldable screens.
