This guide will show you how to enable and and use Personal Hotspot on iPhone 4. This feature is presently available only on the Verizon iPhone 4(iOS 4.2.6) and GSM iPhone 4′s running iOS 4.3 beta. When iOS 4.3 will be released for everyone it will be available to all iPhones.
You can only enable mobile hotspot on your iPhone if your carrier allows tethering. If it does you are in luck. Earlier iPhone had the Internet tethering feature but it could only be used via USB or bluetooth therefore limiting the usage on laptops and desktop computers. Now with the addition of wi-fi hotspot you can share the internet with other devices too like iPod Touch, iPad and other smartphones.
How to Enable Personal Hotspot:
Go to Settings > General > Network > Personal Hotspot on your iPhone 4 and tap on the switch to turn it On.
You will be asked to enter a Wi-fi Password.
Enter your password and tap on Done. You will then be asked how do you want to enable the mobile hotspot. Usually I go for Wi-fi and USB only. It will turn on all the radios that are turned on at the moment and also allow you to turn on the ones that are off, if desired.
You can now connect any device by selecting the wi-fi network we created above. It will have the same name as your iPhone.
Once any device connects to your personal hotspot, the status bar on your iPhone will turn blue. It will also show the number of devices connected. You can connect a maximum of five devices.
The hotspot will automatically turn off after staying idle for more than an hour. This will save your battery from draining. After you have enabled Personal Hotspot once, it will appear on the first page of Settings app and you won’t have to travel through multiple panes to enable or disable it.
