Is the current insider preview fast ring update the "final" release that was featured on the new 950s? I know windows will never be "final" now as it's digressed into eternal beta, but, if i stick this update on my phone can i consider it windows 10 mobile official? also, when official updates come in the future, will it be okay if i uninstall the insider preview? will updates come straight to my phone? or will i have to enroll in the insider preview to get updates? i'm a little confused by this. feels, messy.
