In fact though, FRG01B has been sent out from Verizon's servers in at least two different forms during the run of its OTA. I received them both multiple times over a period of two days. Functionally they may have been the same, but they were extremely different in size, contents and installation processes.
The point I'm trying to make is that until the actual FRG22D OTA send from Verizon's servers is offically completed, we won't know exactly what form(s) this OTA will be in. Currently we see it as a patch. We may also see it as a complete send, or in some other form that we haven't imagined yet.
From previous experience, Verizon has proven itself to be free to send its OTA builds out in whatever form they choose. So insisting that this OP's version of FRG22D is the only way that Verizon is going to send it is at least premature, and may prove to be totally wrong altogether.
That doesn't mean this isn't a good FRG22D build. It is available on Google's website, and as such it has some validity. It just means that we don't know if it's the only FRG22D build, or even if it is one of the FRG22D builds that Verizon will send out in the actual OTA send. There is no crystal ball that can read that future.
