Aren't you concerned that this year's iPhones won't have 5G? You'd be stuck with 4G for a few years.
No. Because 4G works fine and 5G will bring no perceivable benefits for users. It's just a number on a piece of paper that spec whores can brag about.
Perhaps you should also ask Samsung that question. I mean, 3 out of the 4 S10 models they sell DON'T have 5G. I guess they're all "stuck" with 4G for years as well?
