Apple has released yet another beta of the iPhone OS 3.1 along with a new SDK. Developers can download the latest build from the Apple Dev page. While the changes or improvements are not clear, it is said to bring video APIs for the development of augmented reality apps.

The earlier OS 3.1 builds had brought some interesting features like allowing developers to access the device over Wi-Fi instead of USB, video editing features and support for Voice Control over Bluetooth headsets.

Committed to the fortnightly iPhone OS release, Apple has seeded the second beta of the iPhone 3.1 OS to the developers. As with every release, Apple has not revealed what fixes or improvements the new build brings but some users are reporting of internet tethering not working on AT&T network. Currently, internet tethering is not permitted on AT&T but users have found workarounds to enable tethering on standard data plans.

UPDATE: Another feature unearthed is that it allows developers to work over Wi-Fi. It works the same way as connected via USB but is a bit slower than the wired connection and sucks up more battery since it uses Wi-Fi radio.
