FaceTime was recently introduced by Apple on the new iPhone 4. This new feature is only supposed to work on wifi, which can be quite inconvenient if you feel like having a FaceTime conversation while on the road.

In order to get the following trick to work and allow you to use FaceTime over 3G, you need to have the tethering option activated. If you’re in the US, the official tethering plan with AT&T costs an extra $20/month. As soon as the iPhone 4 is jailbroken, I’m sure apps such as MyWi will do the trick.

I haven’t tried this myself but Justin, the iDB reader who tipped me on this, assures me it works. Justin tipped me several times before and I trust him about this. These instructions to get FaceTime to work on 3G are for Mac. I’m sure you can do the same with a PC. If you know how, feel free to comment on it.

Step 1: On your iPhone 4, go to Settings > General > Network > Internet Tethering > Connect via USB. In System Preferences on your Mac, go to your Network preferences. A new “iPhone USB” connection should appear in the left pane.

Step 2: Still on your Mac, go to the Sharing preference pane and check the Internet Sharing box to share your USB connection over AirPort.

Step 3: On your iPhone 4, connect to the network you just started sharing. Done!

This basically lets you use your own 3G connection as if it was a “normal” wifi connection.

After that, you can use FaceTime on 3G all you want. Justin says it can be a little slow but it worked pretty well overall.

Try it on and tell us what you think.

    How do they figure these things out amazing

  • Saice

    So if I activate my internet tethering it means I have to pay an extra 20$ a month?

  • Iphonerd

    Haha ur most hit blog is how to use iPhone without data plan.. Here comes another 20 bucks for tethering… Secondly as far as I understood u still need to connect USB cable to Mac … Not sure abt that part …. Better wait for another option to come out 🙂

    turning internet tethering on doesn’t mean AT&T will do it to your account.

  • caddouch

    why did ClawPack disappear from the internet , how to get it and from where , plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz

  • Can’t you just use like 3G unrestrictor to make it think like it’s on wifi??

  • BBYM

    @sean There isn’t a jailbreak for iPhone 4 yet.

    • lopo

      yes there is (limera1n)


    This DOES work if u can trick iPhone 4 into thinking it’s on Wi-fi. This has already been done with connecting a iPhone 4 to the HTC Evo and then made a Face Time call to another iPhone 4 which was on a true Wifi connection, and well……the quality was very crappy on the 3G part. So for now it’s only worth using on true Wifi 🙁 And I’m waiting on my phone cover to hopefully improve my “death grip” issue, oh yeah, and the proximity sensor….I just luv face dialing! thanks Steve…..and HURRY THE F#*%$K up with IOS 4.0.1!!!

    Yes this works but remember if you have the unlimited data plan by activating tethering option you void your plan and start one of the new plans 200 mb or 2 gb is it worth it

  • i alrady did it…….

    I have already done it. i can let go my nexus one for many reason, even though i got an IP4. I am in love with my nexus ( No charge on tethering) anyway NEXUS ONE TETHERING ON IN MY POCKET AND
    IP4 WIFI CONNECTED WITH ANDROID AP and facetime is on over 3G wifi network. Works fine with my wife’s IP4 facetime.

    Well I figured out how to get FaceTime on 3G without tethering and to top it off while on prepaid !!!

    • Tadashi

      And how ?

  • Thomas G

    When Verizon Wireless released the iPhone 4 on February 11, I got one. Since then, I have jailbroken it with GreenPoison. Then I got the 3rd party app through the Cydia store that tricks the phone into thinking it’s on a wifi connection instead of 3G. Anyway, I wanted to let you know that FaceTime on Verizon’s 3G works great!

  • Jason Masters

    Yeah I facetime on tmobiles edge and it’s still great quality a tiny bit of lag but still great!!!
