Distrusting a whole technology simply because you happened to hear about it first from Elon Musk is pretty silly IMO. Anyway, there's nothing impossible about it. AST Spacemobile has already demonstrated a satellite to ground link with regular cell phone hardware on one end (the space end, since it's easier to launch a phone than a giant phased array antenna, but they also did just launch a giant phased array and will demonstrate that in the next few weeks). The technology works. And T-Mobile obviously believes that too. You don't have to take Elon Musk's word for it.
Apple isn't introducing unnecessary limitations. They launched the best thing that's possible today. But what I'm saying is that it's very likely that in just a few years it will be essentially obsolete.
Where did I say I distrusted anything based merely on Elon Musk saying it? I gave a few reasons why what he claimed should be taken with a huge grain of salt. His own history is a pretty strong recommendation in that regard.
Comparing BlueWalker to Starlink v2 makes no sense, unless you think SpaceX is going to be putting that huge phased array on every v2 satellite they put in the sky? It's a different technology entirely.
Now, maybe Elon was hinting at an impending acquisition? :). That would certainly be on character for him.
You clearly know very little about this. Why are you making statements as if you knew a lot? The Starlink satellites supporting this service will indeed have large phased arrays. Not as large as BlueWalker-3, because BlueWalker-3 is targeting general data service while Starlink is targeting a limited, text-message only service with much less bandwidth (though still a lot more than this Apple thing).
