Staying strong to its promise, Apple is continuing its two-week update cycle for the iPhone OS 3.0. Beta 3 was released for registered developers two days ago along with the SDK.

The new Beta doesn't add any new features but significantly improves performance and bug fixes. If you are already running the iPhone OS 3.0 Beta 3 (Build 7A259), then you should consider upgrading to the latest Build 7A280.

If you are a registered Apple Developer, then you can download it directly from Apple. If not, then you can thank the hacker community for leaking it on the torrent networks. You can download the torrent from any of the following links.

You may also want to check out the detailed instructions on how to install the firmware IPSW and activating it, which we posted earlier. QuickPwn have also released the Jailbreak for the Beta 3, but it only works on iPhone 3G and iPod Touch 2G for now. You can download it from here, but be warned that it may permanently block your device from being patched via Yellowsn0w in the future.
