I'm not usually this kind of noobish, but this is the first time I was tempted to install a GM build of software through unofficial means ahead of its public release. I know a GM is bit-by-bit the same final OS that will be released to the public, but does the device "know" in some way that this was not from the official public source and perhaps treats the install differently? Can an OTA update be unavailable to me when an update is released at a later point, perhaps? Or is it absolutely certain my build will be treated exactly the same as if it was installed on the 19th? Thanks for your help and I hope my next questions will be less annoying.
