Recently I've updated my iPhone 4S from 5.0 to 5.0.1 but the personal hotspot is absent. There is absolutely no active switch within the system menu, attempt to place new APN in cellular data network, difficult to reset and several points. It is totally inactive.
Is there any solution on this problem? Thanks in advance for the advice.
Problem from updating iPhone4s from 5.0 to 5.0
You can try to reset your Network Settings. To do that, go to Settings > General > Reset > Reset Network Settings. Once done, you need to turn off your phone then turn back on again. You should be able to see your Personal hotspot on Settings or Settings > General > Network.
You can also try to go to Settings > General > Network > Mobile Data Network > Look for Internet Tethering > you will then need to provide the APN settings. You can contact your service provider for the details that needs to be set up on the field.
