It's a rather insignificant fact. Sure, if those numbers meant some real-world thing, then it would be good to know, but in this case, it's going to be hard to find a normal user that actually cares. On top of that, location, networking and movement matter, so you could easily simply uncover living habits of users instead of the actual device's speeds. If (and this is unlikely, but bear with) all iPhone users would live outside of extremely well covered areas then they would get different LTE speeds. Doesn't say much about the phone, chipset or provider, just about location. While the article touts Ookla as a good idea because it's real-world speeds, they should also have mentioned that it has no real-world meaning either, as well as having real-world numbers not meaning much in comparison between providers, phones, and locations. At the same time, if the manufacturers of phones use different modems and one is slightly faster than the other, good on them, but who cares?
