I just got a series 0 watch (aka the 1,2 version) and it's saying i need ios 10 in order to pair. Now i have an iphone 5 with 10.3.4 on it, but each time i try to pair the watch to the phone, it says the iphone is out of date. is there a step i am missing? do i need to disable icloud, or cellular service? i'm at a loss on what to do.
