I quess I'm missing something basic, but here goes. I have the Personal Hot Spot option on my iPhone4 and iPhone5 and it works just fine on both. Whatever other devices I'm using at the time will recognize the iPhone as a WiFi source. My question is, why doesn't the phone itself recognize the Personal Hot Spot as a WiFi source? In other words, if I'm out of WiFi range for the phone, why can't I turn on the hot spot and have WiFi capability?
