I just restored my phone yesterday from fresh and updated it to the beta 2. I only connected the hotspot to my iPod the next day. When I came to school, my iPhone was instantly connected to everyone's iPods, even some of the iPads! I didn't even add any of them to my personal hotspot, is there a way to control who can use it? I just got a text saying I've already used 80% of my data... :/
