I ended up buying the 6 64GB but I'm still concerned about RAM. I know it isn't a problem right now but do you guys think the phone will run smoothly on IOS 9 or even 10 when they come out?
I'm worried the 6S will have added RAM so the next versions of IOS will be designed for that and not run well on the 6.
Your phone is already obsolete before you even bought it.
Apple are already working on the next two iphone.
