I use Personal Hotspot a lot on my iPhone 3GS because my iPad 2 does not has GSM/CDMA connection features. It just has Wifi connection only.
So when I want to connect to the Internet but there is no Wifi network available, I will turn on my Personal Hotspot on iPhone and connect my iPad to the hotspot via Bluetooth.
But then, suddenly my Personal Hotspot option (shown above) was missing from the Settings menu. Supposedly the option is available under Wi-Fi option but it was not there. Reboot the iPhone also not successful. So, what’s next?
