Apple released iOS 4.3.5 today and the good news around is that the Redsn0w jailbreak can still be used as a tethered jailbreak option for the iPad 1, iPhone, and iPod Touch. The iPad 2 is still not a supported device. Let’s get started!
Update your device to iOS 4.3.5 using iTunes or download from official direct links here
Download and run Redsn0w 0.9.8b4
Once in Redsn0w, click browse and point it to to iOS 4.3.4 ISPW file for your device. You can find direct download links for iOS 4.3.4 here
Redsn0w will verify the firmware. Once verified Click Next.
Be sure to select “Install Cydia” on the next page with a check mark.
Redsnow will now guide you in putting your device into DFU mode to complete the jailbreak.
Once done, you will have a tethered jailbroken device. Remember, this means that is must be connected to your computer to boot. Have fun!
