Tethering Hack For iPhone Killed In Firmware 3.1

Today Apple released its highly anticipated Firmware 3.1 update for the iPhone and iPod Touch but raised concerns with some as to whether or not the tethering hack would work any more. After upgrading. I went in to the network menu and tried enabling tethering but noticed the menu item had simply disappeared. Unfortunately I wasn’t able to downgrade or re-enable tethering again.
