Following closely on the official release of iPhone OS 3.0, Apple has seeded a developer build of version 3.1, build 7C97D, along with the SDK.
The point release appears to be more than bug fixes, too. A number of sites, including Gizmodo, are reporting features like:
- Faster boot time
- Bluetooth voice control
- Access to video editing through APIs for third-party developers
- Non-destructive editing of video by allowing saving of copies
- Fraud Protection, or phishing warnings, as an option in preferences for Safari
