Until last week when the iPhone 4 was finally jailbroken, your only option to tether the iPhone 4 was to go through the official, legit and expensive way: AT&T. If like me you think that an extra $20/month just to tether your iPhone 4 is a little too much, we’ve got a solution for you. It’s called MyWi.

We’ve talked greatly about MyWi on iDB before but for those of you who just arrived let me tell you briefly what it does. MyWi is an app that let’s you turn your iPhone into a wifi hostpot. Turn it on and share your iPhone Internet connection with computers around you. That’s how simple it is.

Tethering Your iPhone 4 Using MyWi

Step 1: Make sure your iPhone 4 is jailbroken (see iPhone 4 jailbreak instructions)

Step 2: Launch Cydia and search for “MyWi 4.0”.

Step 3: Download and install the free MyWi trial then reboot your iPhone.

Step 4: Launch MyWi and tweak the settings to your liking:

  • Change the hotspot name
  • Change the channel
  • Enable Wep security
  • Enable USB/Bluetooth tethering

That’s it. You can now tether your iPhone using MyWi. Your iPhone doesn’t even have to be plugged in your computer. You can just use MyWi as a hotspot, but remember it will drain your battery like crazy.

While MyWi is not illegal in itself, AT&T (or your local carrier) might have a policy in place to prevent you from using apps like MyWi. As long as you don’t get caught, it’s all good…

If you want to keep MyWi after the 10-day trial, it will cost you about $20. Although it comes with a hefty price, I believe MyWi is one the best jailbreak apps out there.

UPDATE: There are cheaper alternatives to MyWi. Click here for more info.

    I read through this entire thread and it became hilarious when the attacks on Tethermaster began.
    @ Tethermaster, thanks for you explicit breakdown of how tethering work. You know your stuff!
    @ The not-too-tech-savvy, take more time to read earlier posts, so u dont ask question whose obvious answer will be to refer you back to earlier posts :).
    @ The fiesty attackers, “those who live in glass houses dont throw stones” and “it is a crime to be lawful in a lawless society”. You shouldn’t think you can rain insults on Tethermaster and expect him to say “Thanks”.
    @ The curious others [on a quest for tether-know-how], who ignored the fiesty attackers and got the discussion bak on track, at least you got the answers you sought.

    Tethermaster you are a genius dude…and also what you was saying in every post was understandable if they didn’t understand they clearly couldn’t possibly make it out of high school.

    Tethermaster, I am a Verizon customer and am thinking about upgrading to an iphone 4 when they are put up for sale on February 10, 2011. Do you think I will be able to jailbreak the iphone 4 and then download the Cydia app and have “free” wifi with Verizon? Or do you think they may have a block or something on stuff like that so people can’t do it?

    • Wifi has always been free on the iPhone… as well as every wifi phone out there… there is no need to jailbreak to get wifi on the iPhone..

    I am confused then. Why does step #1 say to make sure your iphone 4 is jailbroken?? And then u can click a link for those instructions…..

    I am confused then. Why does step #1 say to make sure your iphone 4 is jailbroken?? And then u can click a link for those instructions…..I thought it was going to cost $20 a month to have wifi available on the phone otherwise. That’s not free.

    • It does not cost $20 to have wifi on your phone. Your phone comes with wifi from the factory and is free to use.
      Jailbreaking and wifi have nothing to do with each other…

    you guys are retarted wifi teathering so you can use your iphone like a wireless modem. therefore you can use internet from ur computer like you were near a wifi hotspot but your phone is the hotspot, this way you can use the iphone to connect to the internet when you are….for example on the road near no hotspots

    • Ahh, your retarded for writing up that entire paragraph about a topic that MOST of us already know… This is nothing new, why even define wifi tethering, we already know what it is, some just want to know HOW its done….

      • God

        You guys are both fucking retarded.

  • grazsootz

    hes not talking about connecting to wifi with the iphone
