I've currently got an iphone 6, and my mother has been thinking about switching from an old nokia to a newer smartphone. I think the iphone 6 is great but i've had it for a few years. We've looked at the Iphone 6s, but my worry is that it might not be supported in 2 years time. I do not know this, but i'd like to know. Will she need to worry about it not being supported in a few years? She will probably be using it for a while if she ends up buying it, so having it be outdated in 2 years would suck.
