iOS 4.1 Breaks Jailbreak and Unlock – via Dev-Team
Like most firmware updates… iOS 4.1 breaks the current jailbreak and unlock. This is especially true for unlockers due to the fact there there is no way to revert your baseband. I’m sure the guys over at the Dev-Team are working on updating the jailbreak. We will keep you informed on how they are doing. Below is what the Dev-Team has to say about upgrading to iOS 4.1.
Apple has released iOS 4.1 for the iPhone and iPod touch bringing numerous new features including a fix for the iPhone 4 proximity issues. This update contains improvements, including the following: ● Game Center - Send and receive friend requests - Invite friends to multi-player games over the Internet - Play multi-player games by auto-matching with other players - View LEaderboards and Achievements - Discover new games from friends ● High dynamic range (HDR) photos on iPhone 4 ● Support for TV show rentals on iTunes ● Ability to upload HD videos to YouTube and MobileMe over Wi-Fi on iPhone 4 ● Additional support for AVRCP-supported accessories, including next & previous track control ● FaceTime calling directly from Favorites ● Bug fixes, including - iPhone 4 proximity sensor performance - iPhone 4G performance - Nike+ iPod fixes - Bluetooth improvements Products compatible with this osftware update: ● iPhone 4 ● iPhone 3GS ● iPhone 3G ● iPod touch 2G Game Center requires iPhone 4, iPhone 3GS, iPod touch 2G or later As usual jailbreakers should remember not to update to this firmware until the iPhone Dev-Team provides a proper update path.This time of year there are lots of new iPhone owners, and not everybody knows that accepting new iOS updates is the surest way to lose your jailbreak and/or unlock. While those of you who have Cydia or TinyUmbrella backups of your FW hashes will always be able to get back to 4.0.1 if you make this mistake, this doesn’t hold for unlockers. There’s currently no known way to revert your baseband — if you update your baseband you’ll lose the ultrasn0w unlock, possible forever.Please stay away from this 4.1 release until a safe jailbreak procedure (which also preserves ultrasn0w) is developed and released.P.S. There are a tiny number of iPhone3G owners who can revert their basebands due to a flaw in very early bootloaders…you will already know if you fit in this category!
