I'm stunned I'm even still having this conversation. It should be crystal clear by now that my point is simply this (yes, using a bit of hyperbole because after all it's just MacRumors):
Apple has repeatedly said its rationale for this policy is that cellular service is (has been) essentially too slow and unreliable to update system critical files on the fly. They're too big and package verification is too important. This clearly implies that broadband-level cellular service is all that's necessary for this policy to be revoked.
In both the US and many parts of the world, including Europe, ALL networks currently provide broadband-level service to many if not most people. The new band for T-Mobile will FURTHER IMPROVE speed and reliability for T-Mobile, which already is essentially tied with Verizon for speed and reliability. Moreover, when 5G hits THIS YEAR AND NEXT, many people will never pay for wi-fi again (note that Verizon Wireless believes in 5G so much they're actually launching IN THE HOME before launching with mobile devices).
The new T-Mobile band is an example of the ongoing erosion of the basis for Apple's policy, which is restrictive for many users now, and with 5G in the coming MONTHS (not years) will become perhaps entirely disqualifying. There will be a tipping point very soon where Apple must acknowledge its policy is based on outdated information and is no longer necessary or indeed beneficial.
No. I don't think one new T-Mobile band necessarily requires a revocation of this policy. If I even said that, I was clearly exaggerating to make the point I make here and have made in several posts now.
I mean honestly - did you not see my point?
