As it was predicted Apple released iPhone OS 3.1 if you haven’t download yet, then download your copy from here. OS 3.1 contains a baseband update 5.11.04 BB for iPhone 3G and 3GS. If you are curious to update your iPhone then hold your horses and read this post. First of all if you upgrade iPhone to OS 3.1 you Baseband will be locked permanently and there is no downgrading option available at the moment. Musclenerd tweeted last night about the jailbreak, unlock progress and he showed his iPhone 3G OS 3.1 unlocked with 04.26.08, so wait for Dev team team to release the updated version of Pwnage Tool.
iPhone 3G, 3GS Unlocker should be more careful to OS 3.1, because if you update to 3.1 your baseband also update to the latest baseband and the current Ultrasn0w is not capable to unlock the baseband 5.11.04. Now the problem is you can’t unlock baseband 5.11.04 with any utility in the wild.

Features of iPhone OS 3.1 Via iSpazio :
- Increase the speed of Boot (timing of ignition decreased)
- Have made several changes all’AudioToolBox the OpenGL | ES, the Quartz Core, the IO Kit (editor of images and video.) Soon we will see how they affect applications.
- Added the new option “Save and Copy” while editing the video. In Firmware 3.0 when a video is cut completely lost the original file and saved only one remained unchanged. Now it is possible to maintain both, so we can send short video via MMS without deleting the whole.
- If you hold down the Springboard icon, not just start swinging the iPhone will emit a small vibration
- Solved the problem of multiple SMS: In Firmware 3.0 when multiple recipients, the message is automatically transformed into MMS. Now it is possible to send sms to multiple people without recourse to the small tricks that you proposed.
- Better reception of network
- Improved WiFi Reception
- The Voice Control also works with Bluetooth
- The modem version is updated to 5.08.01 (which probably will not work ultresn0w more)
- All’SDK added new API that allow developers to access and edit the video, which will arrive soon in AppStore applications to edit video, add effects, frames and more.
