I recently downloaded the new 4.3.3 update, and can't seem to figure out personal hotspot. I understand that my connection creates a wi-fi connection for other devices, but where does the wi-fi come from? Does it just create wi-fi from my basic internet? With personal hotspot turned on, could I use apps such as FaceTime even if I'm not in a wi-fi zone?
