I updated my iphone 4 yesterday and i wanted to see the hotspot feature but when i go into settings i see the new location service thing but isnt personal hotspot so pose to be there too. i only see it when i got into network settings where it says set up personal hotspot after i do that will it appear on the first page of settings. And when i do press it i need to contact my phone carrier why is this so i bet i have to pay for this feature -.-
