How to turn personal hotspot on your iPhone 4 on?

I want to use my Internet from iPhone 4 on my laptop on. How do I do this? Please step by step.

The personal hotspot feature is only available with certain iPhone mobile phone sim contracts.

If you have a contract which includes the personal hotspot feature got to Settings. In the menu, in between 'Bluetooth' and 'Carrier', there will be an option for 'Personal Hotspot'. Simply select this option and turn the Personal Hotspot 'ON'. Note the Wi-Fi Password.

  • What additional cost may occur from making my iphone a personal hotspot? I turned on the personal hotspot option in settings on my iphone but it says additional costs may occur. Does that mean it costs money for me to connect my other devices or just if i exceed the amount of 3g i'm paying for.
  • Is the personal hotspot option on the iphone safe? I just learned i can use my iphone as a hotpot and i freaked out! Apparently you go settings, general, network, the it says personal hotspot! So is it safe? More importantly does it cost a lot or free?
  • If you have a personal hotspot does that make your 3g Internet faster? I'm new to this whole personal hotspot thing but I do have some information that I know like how it acts like a personal router to other devices such as Xbox, ipod, computer, etc. The only questions that I don't know are the ones below. -would it make my iPhone 4S much faster? -does it cost money to get it and if so how much? Oh i'm on sprint btw!
  • If someone uses your personal hotspot of iphone 5 what can they see? I was using my personal hotspot via USB and then I realised it had 2 connections. I immediately turned it off. However now I'm afraid because after this I got a call off a blocked number. If someone hacked into my Wi-Fi from my phone would they be able to see contents such as pictures on my phone? I'm very scaredz thank you
