Apple has just released the newest beta of iPhone OS 4.0 and it comes with a long-overdue feature: Internet tethering from AT&T.
Tethering was first revealed last year with the iPhone OS 3.0. However, while some international carriers supported Internet tethering, AT&T did not because its network couldn't support the wireless traffic. The same concerns with the network's durability delayed the rollout of MMS.
Now it looks like AT&T is finally confident that it can support tethering for its data-hungry customers. Among the new options in the iPhone OS 4.0, beta version 4 is the option to set up Internet tethering with AT&T via phone or web.
The inclusion of tethering in the iPhone OS 4.0 beta doesn't necessarily mean that it will actually come with the final version of iPhone OS 4.0. However, it's the best sign yet that AT&T is finally getting its act together and will soon support a feature that it should have supported a long time ago.
