    I dont know for the other iphone models, but for the 3GS in order to get tethering/mms working you must...

    Tethering - on your iphone safari browser got to: help.benm.at/help.php
    go to mobileconfigs section and download appropriate carrier..

    downgrade itunes to the 8.2 beta
    then update using the modified ipcc, which will give you the 5.0 carrier.

    Under general--network--cellular data network.. your mms settings are:

    APN - wap.cingular
    Username - [email protected]
    Password - CINGULAR1
    MMSC - mmsc.cingular.com
    MMS Proxy -

    Then take out your SIM card and put it in another att phone, send some texts and mms with it.. go to mymedianet.wireless.att.com on your computer, enter your phone number, then the code..

    Once all that is done put your sim card back in your iphone and thats it..

    Also make sure under the cellular data, Visual Voicemail that the APN is acds.voicemail
