probably they will release only the gm’s ipsw, not ota
That’s possible, but again that seems really unlikely. As of right now they are essentially saying that they are done with 13.0 and that it is ready for release as no more beta’s will be released with 13.1 out there. Beta 8 is ok, but its not ready to be released to the public.
If Apple releases a public beta 13.1 today they are essentially saying that they are clueless and don’t know what they are doing in regards to this software. If they don’t then who knows what they are thinking.
