i got the new ipad and i set the hotspot feature on it. than i connected my iphone 4s and was able to use the ipads hotspot just fine. problem is that when i leave the house and come back later, the iphone does not automatically connect to the ipads hotspot, i have to turn the ipad on, goto the hotspot tab (which is always on) , and then the iphone finds it and connects. does anyone know of a way to keep the ipads hotspot feature always "on"? thanks
