Internal "subframe" will evolve while external looks the same.

AIP technology will likely to be late (due to FCC testing) for mmWave 5G.

Look for initial Dec release to be sub-6GHz 5G since no mmWave infrastructure is available in US

Spring time 2021 release for Chinese New Year would be the true target for mmWave 5G.

Nice. That video goes into some serious detail.

I watched this video twice and can’t find any reference to the AIP or “internal BMG subframe.”

This says AIP will be integrated into the "internal BMG subframe".
This video tells it all.

The iPhone 12 "smart connector" may actually be a heat sink exit using composite materials in the mid-frame and a composite outside frame. See the photos below. (The smart-connector idea was just a guess from Joshua's video (see below), and in fact is much smaller than the actual smart connector found on the most recent iPad. The area in question is the small pink oval found in the last photo. Compare it to Figure 6A in the first photo. Same location.)

The first image below is from an Apple patent for a heat-transferring composite mid frame.

The images of the battery layout and "smart connector area" are screenshots of the video posted by Joshua yesterday (see below).

Finally, recall Gamesc's recent Apple patent post (157252210), in which the first point of the patent is this:

1. A housing of an electronic device, comprising: a metal shell including a first material having a first set of material properties and a surface having a substantially curved shape, the surface at least partially defining an exterior surface of the electronic device; and an interior portion including a second material having a second set of material properties independent of the first set of material properties and at least partially defining a feature, the interior portion being bonded to the metal shell and disposed interior to the surface. http://appft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PG01&s1=%22Metallic+glass%22&OS=%22Metallic+glass%22&RS=%22Metallic+glass%22



So, the worst-case scenario appears to be that only a tiny part of the mid-frame and a tiny dot of the external frame are liquidmetal. Best case, the entire external frame and most of the mid-frame are liquidmetal except for an even-more conductive heat-transferring metal.
