And not even that hard to find: "alibaba MSM8916 LTE" on Google and lo and behold: https://www.alibaba.com/product-detail/TIANJIE-Qualcomm-MSM8...

$5.92 each for 500-2999 orders. What a time to be alive.

How much work is it to rip one of these open and reprogram?

		probably 2 screws at most or some glue/snaps, then put a jtag brush over the contacts, do some sort of unit test and you have a unit. Could take a few hours with a motorized screwdriver and a simple specialized CLI program for programming/testing
