  • How to Enable Tethering in iPhone OS 3.0


    Tethering has always been one of the 'most-wanted' features for the iPhone. Though it was felt that AT&T's monopoly over iPhone in the US has prevented it so far, but according to Apple's Scott Forstall, Apple added the feature in the 3.0 OS. Still, it's kept "disabled" in the 3.0 beta versions distributed by them so far as they are yet to co-ordinate it with the mobile carriers.

    Unknowingly, Steven Troughton Smith was tweaking the APN in carrier.bundle and suddenly found that he somehow enabled the Tethering preference! From the screenshots provided, it seems that there will be two modes- USB and Bluetooth tethering. As he's not yet clear how he activated, so there are no details from him on how to do that right now (unless he or someone else works it out).

    Luckily, someone found this out. You may enable it if you have access to developer's beta by following steps below.

    Step 1: Check if you own a 3G iPhone. If you're on EDGE (as I am): sorry. Tethering does not seem to work with EDGE phones.

    Step 2: Check to see if AT&T is your carrier. If it is: sorry. AT&T will not let you tether.

    Step 3: Navigate to ~/Library/iTunes/iPhone Carrier Support. Notice the spaces in that last folder name! If you're at the command line, use backslashes to escape the spaces, i.e. cd ~/Library/iTunes/iPhone Carrier Support. You will find a file with an ipcc extension. Copy that file: e.g. cp foo.ipcc foo.ipcc.original. This creates a backup for when you mess up.

    Step 4: rename the ipcc extension to zip. For me that was ATT_US.ipcc renamed to ATT_US.zip. (Did I mention how I'm on a 1st Gen iPhone with AT&T?). Unzip it. This creates a new folder called Payload.

    Step 5: Navigate into Payload and then into the folder under that. Mine was called ATT_US.bundle. Yours will differ. Inside that folder you will find three files that you will edit: Info.plist, version.plist, and carrier.plist. Open all three in the Property List Editor that comes with the dev tools on a Mac.

    Step 6: In Info.plist, change the CFBundleVersion to 5.0. Save.

    Step 7: In the version.plist, change the CFBundleVersion to 5.0. Save.

    Step 8: In carrier.plist do the following and then save:
    (a) Add a new dictionary to the apns array:
    apn = internet
    password = password
    username = iphone
    (b) In the wap dictionary (mine is wap.cingular, sts's was wap.dol.ie), add a new pair. Do not edit the password or username:
    type-mask = (NUMBER) -2
    (c) Add a new pair at the top level dictionary of the carrier.plist file. (We're not sure this is strictly speaking necessary but go ahead and do it.):
    AllowEDGEEditing = (BOOLEAN) YES

    Step 9: Zip up the Payload folder in which you just made your edits. Rename it to the same name as the original ipcc file. (For me that was ATT_US.ipcc).

    Step 10: Connect your iPhone to iTunes.

    Step 11: In the Summary tab, option-click "Check for Update". Navigate to your ipcc file, select it. It takes no more than a second or two to update.

    Step 12: Reboot your iPhone.

    Step 13: In prefs (on the phone) navigate to Settings > General > Network.

    Step 14: Let me know how this worked for you.

    HOW TO FIND A CARRIER IPCC FILE:

    curl -s -L http://phobos.apple.com/version | grep -i carrier
    Though, it is not very clear yet that when Apple will finally release 3.0, will Tethering be added but if Apple gets its say, we will see this wonderful feature added soon!

      Yah, if you are not a AT&T customer and always have 3G access where ever you are.

      But, I do agree - I still like free! Hope they get it working for the non-3G access!

      Awesome guide thanks Mr STS . FWIW my wap dictionary was:

      apn=www.iphone-vodafone.co.nz
      password=
      username=

      Oh and
      (c) Add a new pair at the top level dictionary of the carrier.plist file. (We're not sure this is strictly speaking necessary but go ahead and do it.):
      AllowEDGEEditing = (BOOLEAN) YES
      was already there

      I just tried that IPCC and I just keep getting this error message:

      Bluetooth network failed.

      Failed to open a connection to the network service.
      Your device may have reached its maximum number
      of supported network connections.

      And the USB tether appears to do nothing. It doesn't show up in Network Preferences and I have no option to add a USB network interface or anything.

      Apple Developer Connection

      They provide a lot of resources for people who want to develop. You can ge the SDKs for free when they are released, but can't sell on AppStore, or you can Pay the $99+ dollars to register, and release on AppStore, and have access to the betas.
      which tool would you use? xcode?

      It is the ability to use the internet from your phone on a computer. So wherever your phone has coverage you can have internet on your laptop

      Soon you won't need to carry a laptop as the iPhone will be capable of most stuff you can do on a laptop, I hope the iPhone will be anyway

      God Knows ATT is sooo going to charge a arm and a leg for Tethering.I'm happy there finally allowing Tethering, but i hope it will be a decent price and not something that's going to hurt our pockets.

      I got it to work with ATT but when I did I was no longer able to get voice mail or MMS. Anyone else having the same issue?

      I had no BT connection (same as someone else) but never had MMS appearing as it is shown elsewhere. Odd given the network here definitely supports 'PXT'

      Is MMS controlled via the same bundle then?

      How did you get MMS to work with the 3.0 Beta? Mine tries to send and I get an error message and asks if I want to retry. Do I need to change my plan with AT&T. Sorry if this is the wrong forum.
