You might have only just got used to the sizes of the iPhone 6 and the iPhone 6 Plus but we're already thinking ahead to the iPhone 6S (or iPhone 7?). The latest gossip from insiders is that this year's handset will boast 2GB of RAM compared with the 1GB stuck inside the 2014 editions.
That's more memory to deal with multiple apps running at once as well as larger images and video files. Doubling up on memory should mean a much faster and more capable iPhone, particularly when it's paired with the usual CPU upgrade that Apple treats us to. The iPad Air 2 features 2GB of RAM too.
