Let me begin with saying that you will need a Jailbroken iPhone for this Tethering to work with any computer. It was pretty easy to jailbreak iPhone 3G when you were on 2.2.0 firmware. But with 2.2.1 iPhone firmware, it’s  bit more tricky. If you want to

with 2.2.1 firmware, check this post


on iPhone Dev Team’s blog.

Now, here is how to Tether your iPhone 3G. (Note: this works with Mac machine only)
  1. Go to iPhoneModem.de

    and download a free app called iPhoneModem. (You can donate few bucks if you like)

  2. Once you jailbreak your iPhone, open up Cydia and install the package called iPhone Modem zsrelay. Install another app called OpenSSH.” With another app called BossPrefs, you can check if SSH is running.
  3. Install iPhoneModem helper app and run it. Go to “Settings” under the little iPhone icon that just appeared in the status bar.
  4. Fill in the following fields:IP-Address of Mac: Leave the default value (
    Password of Mac: Your admin password
    WLAN Name: The name of the ad-hoc network that will be created – your choice
    WLAN Password: It must be 13 characters-your choice as long as it’s 13
    SOCKS Port: Leave default (9999)
    iPhone root Password: alpine (as long as you’re running 2.x firmware)
    iPhone Mac Address: Found under Settings – General – Abou.
  5. Once your config is saved, go to “start connection” and follow the instructions. Your laptop will create an ad-hoc network, which you will then join with your iPhone. Once this is done, you are done. You can tether your iPhone 3G connection to your laptop. :)
