iPhone Shipping/Delivery time question

I made the JUMP from S24 Ultra to iPhone 16 Pro Max (even though I have a second line for work and will still be using another S24 Ultra, lol).

Question regarding shipping/delivery with iPhones...historically, Samsung Galaxy devices have been delivered 2 to 3 days before the official release date when I've ordered from T-Mobile. For example, if next Friday were the release date, I'd receive the phone on the Wednesday prior.

Is this the case with iPhones and T-Mobile?

EDIT/UPDATE: I just dm'd T-Force and they stated that they'll start "shipping" phones on launch day. Honestly, I don't believe that. I'm almost certain we'll receive our devices on Friday, at the latest.
