> I can't imagine being locked in till it dies, because as you said, the iPhone is such a miserable product. I'm sure you could resell and get a flagship for a similar price. You'd still net loss, but IMO it would be better than keeping the phone since you don't like it.

I'm not locked to it but honestly I spend so little time on my phone that it's one of the smaller problems in my life. I do despise it, but not enough to sell it before I can't use it anymore.
