Hey guys, There are many threads on tethering right now, but I wanted to post the method that seems to work for most everyone. I'll quote the original author: The file he refers to is attached to this message (Thanks again, zilian77). Note: If you don't understand any of this, chances are you probably shouldn't be doing it. If IPC is "Greyed Out": When alt+clicking the restore iPhone to put the carrier settings and it is greyed out, remove the file from the mounted disk image first, then select it (from your desktop, for example). And I reiterate, MMS IS NOT WORKING. We have yet to figure this out. If anyone does get to to definitively work, post here and I'll update this top post. So far we have gotten the camera icon to show up on the Messages.app.
