    hi - I had this working on 3G XP - but the update seemed to override the entire thing - when I downlaod the config file on my iPhone Tether no longer shows up AND when I look at the Profie Details of US AT&T Advanced settings the Name shows wap.cingular HOWEVER the UserName: shows a blank ??? Per the other writings in this blog and generator.php doesn't seem right AND you can NOT change this configuaratin from the iPhone?

    I used an ipcc that I found on OSX daily, then had to reinstall the ipcc for tethering, in anycase, I've got MMS, tethering, and visual voicemail still works just fine. It may help you to use the restore button in itunes if your itunes is already prompting you to update to 3.1. I finally have the phone that I paid for!!!!! Now if we can just get the hacks for 3.1 so I can get a 3GS.

    i have an 8gb iPhone 3G OS version 3.0 (7A341) and i was able to send MMS to asia and canada while using internet tethering. all i did was follow the instructions for the tethering and mms and installed everything from my iphone. i just made sure i restarted the iphone on tethering and restarted the iphone again for mms.

    I am having troubles installing the AT&T carrier files onto my phone. When I press Option while checking for updates, no window indicating that I can choose a file to upload appears. Is this because my phone is not registered?

    Any help appreciated!
  • jeff
    use the restore button and option.
  • Kirk
    Yes, a little confusing: Am I supposed to enter a username and password for each section (i.e. cellular data, visual voicemail, and mms)?
  • ben
    so after the install my visual voicemail doesnt work, and MMS doesnt work either

    iPhone 3G, upgraded to 3.1 using iTunes, then downgraded to 3.0.1 using benm's tutorial, then applied the MMS instructions above, it works in WiFi and ATT's network. 30 minutes later I was unable to send MMS pictures, it said message failed to send, then I tried again, and the MMS messages went just fine. Seems to be working now. Thanks for the instructions!
  • Tux
    Now tethering and MMS on 3.0.1 on iPhone 3G. Worked like a champ. Thanks.
    note: Had to reinstall the tethering mobileconfig after applying the MMS fix.
