Hi all, At present, I own an iPhone 5 and an iPad Air 1. Both have and still continue to serve me well, and the recent update to iOS 10 continues to improve the experience (although the iPhone has slowed slightly). However, given that iOS 10 does not support the iPhone 4, it would seem reasonable to assume that by next year, my iPhone 5 will not be able to run iOS 11. So, in the event that this is the case, what will happen in terms of mainstream applications such as Facebook, Gmail and others? Do developers effectively cut off their application development to older iOS's, eventually making them practically unusable from an App point of view? In addition, in preparation for the above, would it be a sensible idea to get rid of the iPhone now and upgrade, whilst it is still supported and sellable? If so, is it worth waiting for the iPhone 8? Many thanks, Kind regards, Jack.
