Following the release of iPhone OS 3.1 Beta and iPhone SDK 3.1 Beta, iPhone-focused website QuickPwn quickly provided some of the most visible changes with the new software. The source also points out that those relying on the iPhone Dev Team’s ultrasn0w to unlock their device should temper their update-itchy fingers.

“iPhone SDK 3.1 beta and iPhone OS 3.1 beta are now posted to the iPhone Dev Center,” Apple says on the designated web page. “These versions are for development and testing only and should be installed on devices dedicated to iPhone OS 3.1 beta software development,” the Mac maker adds. “Please read the iPhone OS Pre-Install Advisory and the iPhone SDK 3.1 beta release notes before downloading and installing. Use the Apple Bug Reporter if you discover compatibility or functionality issues while testing with the iPhone OS 3.1 beta release,” the message ends.

As noted above, soon after the news was out, QuickPwn offered some insight as to what iPhone OS 3.1 brought. According to the source, some of those changes include:

- The baseband has been updated to 5.08.01 – ultrasn0w users should not use the iPhone OS 3.1 Beta, otherwise their iPhones could be permanently locked! - iPhone 3GS – When you’re trimming your videos you now have the option of saving the original video by tapping the “Save as copy” button. - Voice Control is finally working over Bluetooth now! - When you move your icons around, the iPhone vibrates. - MMS is enabled by default, but does not work for AT&T users. - The AT&T profile is updated to 4.2. - Improvements to OpenGL and Quartz. - There’s now a VideoEditorController API – Allows third-party apps to call up video editing UI. - Video picker API.

The source further stresses in a separate post that, “If you’re using the ultrasn0w software unlock, DO NOT UPGRADE to iPhone OS 3.1 beta because you may permanently lose your unlock. Apple has updated the baseband to 05.08.01. Remember, even when the final iPhone 3.1 firmware is released, you should not update if you want to keep your ultrasn0w unlock.”
