Every time I turn on my mobile WiFi hotspot on my iPhone, it works great unless I am in range of a remembered WiFi hotspot that iPhone itself can connect to -- iPhone silently opts to use any WiFi data stream instead of my cellular stream, the latter of which I always prefer.
My phone's data connection is much faster than my WiFi connection, and it often takes me a while to realize why my iPhone's hotspot it so horribly slow: it is connected to the very WiFi access point I am attempting to circumvent!!
Is there a way to prevent iPhone from itself connecting to WiFi when broadcasting a WiFi hotspot of its own, without "forget"-ing all relevant hotspot encryption keys?
