  • 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!

      yes, but this is a one time thing. And you can find the patched carrier update online. Just option+update and reboot. After that it's just a matter of plugging the phone to the mac. I used pdanet, and this is a far better solution. Fluid and intuitive. That's the way I like my Apple

      Hi all, thanks for the instructions. I got the tethering screen to come up fine, but after pairing with my macbook pro, I can't connect to the PAN connection. A USB option doesn't come up at all. I'm using AT&T and have the 3.0 SDK installed. Am I missing something?

      I havent had any luck with PAN on my MBP - USB was no problem though, in Network connections just swapping the DHCP to something else then back to DHCP and hitting apply seemed to work sweet? Do you have the "Ethernet Adaptor (en5)" available?

      They won;t have elsewhere to look for another 3 years...
      Hopefully this means free tethering with ATT, but I doubt it :/

      Xcode is one of the tools you use. There is a whole section of documentation and training which is very well done for even a person who has never coded any apps for Mac Platform. Lots of tutorials. XCode is just one of the tools, there are several, dashcode, iPhone Simulator, iPhone Organizer, Quartz... plus much more, and its free to dl.

      For T-Mobile Germany things are a bit more complicated because they do not appear in the list. Here is a howto: FutureTap iPhone Tethering with T-Mobile Germany

      I called them and they added the MMS to my plan and it still didn't work. Got transferred to there tech support and they said they dont give support for 3.0 so mine still dont work.

      Free? No cellular company (to my knowledge) has ever offered a tethering package for free. It is the most bandwidth intensive thing you can possibly do with your cell phone. More users requiring more bandwidth equals more T1s/DS1s at each cell site, which won't come free to AT&T or you.

      No, I want it to connect to the internet when I use the useb connection. My wifi does not connect. I always get "unable to join network ". So it's either 3G which costs, or free wifi I can't get...

      Why not just sort out your WiFi - it's a lot easier than using a wired connection!

      What security do you have on your WiFi at home and what FW on your iPhone?

      WAP on one router and WEP on the other.
      Firmware 2.2 yellowsn0ed

      This happens with EVERY network. The message is the same:
      "Unable to join network "

      Apple/iphone/networking forum is full of threads with this problem...

      Are you using the 3.0 Beta 2 firmware?

      I've got AT&T and i'm running the Beta 2 Firmware. I installed the update that makes tethering possible but i'm not exactly sure how to make it work. Would any one mind make a step by step for getting to the net after you turn the tethering on?
