One of the first things noticed by Gizmodo was a new screen that would let users set up tethering on their iPhone. Under the network settings, there's a tab for "Set Up Internet Tethering." When users click on that, they are greeted with a pop-up message that reads, "To enable tethering on this account, Contact AT&T at 611 or visit http://www.att.com/mywireless." Below the message are buttons that would initiate a call, or take you to that web site.
A few things to keep in mind. Just because the option is there in no way implies that tethering will be included in the final build of OS 4.0 (in the U.S., anyway). The iPhone has been capable of tethering since last year, only AT&T has not enabled the service yet in the U.S. The appearance of this option certainly gives hope to those who want use their iPhones to tether, but it is not a guarantee that AT&T will offer the service any time soon.
Just a few weeks ago, AT&T told tech blog Engadget:
That language says pretty clearly that AT&T isn't ready to offer the feature. Will it be ready once iPhone OS 4.0 goes live to Joe Consumer later this summer? We can only hope.
We understand that there is great interest in tethering but cannot provide any details at this time. We know that iPhone users love their devices and mobile broadband, and that they're likely to embrace tethering just as they have other features and apps - by using it a lot. iPhone tethering has the potential to exponentially increase traffic, and we need to ensure that we're able to deliver excellent performance for the feature - over and above the increases in data traffic we're already seeing - before we will offer the feature.
