    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).

    To all: I have no idea how I did it. Sorry! I was hacking around with APNs in the Carrier.bundle itcc file
    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!

    as long as we still got our phones pwnd we will not stop tehering! .. and i think the only why at&t will let ipone tether, would be if apple gave at&t the reach around the same while tethering testing..lmao!.. dirt bags!

    Tethering is the connection of a non-mobile device to a mobile device for the purpose of wireless Internet access by the non-mobile "tethered" device

    Nothing in the instruction mention accessing the iphones file system. It's all done in the Mac.
    You basically create an itunes update

    Seeing as he has the 3.0 beta, if its a legal version, he's a Registered with the iPhone Developer Program. And as lightning said it is done on the Mac with Xcode tools.

    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.

    Hmm let's see.. a few steps for something free.. or, money on something that's not.

    If you ask me, that's a no-brainer there.
