And you are most likely wrong, Jolly Roger, which Frank Slootweg explained.
But you tried so I'll leave it at that.

Apple is like Ashley Madison, claiming privacy while it's always a lie.
You're logged into Apple tracking servers every moment of your life.

Apple's promise of privacy is as false as Ashley Madison's promise was.

There is no other common consumer platform which requires you to be logged
into it for the basic functionality of the phone - except for iOS, JR.

That you don't understand that fact is indicative of your religious mantra.

That you are unaware that Android sends & receives messages through the
default messenger app without logging into Google servers is clear.

Only Apple requires you log into their mainframe servers for the messaging
functionality that Apple advertises and that you religious zealots love.

It's no longer shocking you don't understand that no other operating system
but iOS requires the user to be logged in 24/7/365 for basic functionality.

Google does not require that login into Google's mainframe servers.
Apple does.

Note: You can say "don't log in" but I've done that. Apple will
unilaterally brick your iOS device if you stop logging into the servers
for a period of time (two years in my case on two different iPads).

There's a reason Apple designed the iOS device to be a dumb terminal, JR.
It can't do anything that you love about iOS without Apple server logins.

So does the iOS cellular MMS service, Jolly Roger. Nobody said otherwise.
It's a necessary evil to obtain cellular phone service with MMS capability.

Ah, but Android's default messaging is not - although RCS may change that.

Exactly.
Without logging into Apple's mainframe servers, all the things you love
about your iPhone instantly cease to exist,. It's just a dumb terminal.

I didn't say that. I said either or.

Either by WI-Fi Internet or by cellular data Internet.

>> b. Wi-Fi Internet connection?

Again, there's the concept of either or that you need to study.

I know how iOS updates and I know how Android updates. You don't.
I just don't deal with iOS messaging since the iPads are just toys to me.

There must be a method on the phone that tells the iPhone which people are
logged into the Apple mainframes and which people are not logged into them.

I'm not sure if you're right. See above.

How does the iPhone know if the iMessage user is logged into the Apple
mainframe servers? I'm not logged into my Messages app on my iPad.

I'm not sure if that's the case, as Frank made an eloquent argument that
the compression to shit of the videos is happening on the iPhone itself.

We're not sure yet where the downsizing to shit happens. Frank's argument
is valid that the carriers don't want to do it as that would negate the
whole point of limiting the amount of data sent to the carriers.

I doubt it. Show me a full explanation on the net where it is explained.

Actually, none of us (including you) knows how it works, as all of us
(except you iKooks) have openly said we're not sure how it works.

You iKooks are always sure but you're always wrong at the same time.
You don't actually know how it works any more than I don't know it.

If you can find an article that explains fully how it works, I'll not only
read it, but I'll be able to understand it - but I doubt it actually exists
since everyone glosses over the critical steps of where things happen.
