I had enabled tethering on my iPhone awhile back, even though I didn’t use it too often, I figured it’d be a good feature to have, and it actually saved me a couple times while I was traveling – allowing me to download a file that I forgot to bring on my laptop, and I also was able to book a plane ticket using tethering and my MacBook.
Anyways, I recently installed the iPhone 3.1 software update and my days of tethering are no more. I also just realized that since installing the 3.1 update, the updated carrier settings from the tethering enabling mobile config file had caused my visual voicemail to stop working (again). I’m waiting on a fix from our buddy Ben M who released the first mobile configs that allowed tethering to be enabled, but it appears that Apple and/or AT&T have made things tougher this time. The one thing that concerns me is the fact that the settings screen now traces tethering data transfer… I’m assuming that AT&T will use this to hit you with a hefty bill anytime you’re using tethering data transfer.
Has anyone found a workaround to get tethering working on iPhone 3.1?
