As said in the article, we've been here before. iPhone tethering was in the last beta, too. It never saw release.<p>AT&T promised tethering <i>by last fall</i>. I find it strange that they're such close business partners with Apple, considering how woefully they under-deliver on their promises, when Apple's MO is basically the exact opposite. The AT&T/Apple relationship has been a black mark on my perception of the company, and I've been an Apple evangelist for 12 years.
I don't think this is any closer to reality than it was 2 days ago. The setting shown in the screenshots are not in the latest beta build I installed on the 3GS. Other developers confirmed that it's not in their build either. I have yet to hear someone say they have it.
