iPhone Dev-Team has released Redsn0w 0.9.8 beta 3 to jailbreak iOS 4.3.4 on iPhone 4, iPhone 3GS, iPad, iPod Touch 4G, 3G. These are the steps to jailbreak iPhone 3GS, iPhone 4 iOS 4.3.4. Steps for iPad and iPod Touch are the same.
Important
- RedSn0w 0.9.8 b3 provides tethered jailbreak for iOS 4.3.4. For those unfamiliar, a tethered jailbreak means you will have to connect your iDevice to a computer, every time you reboot, in order to boot it into jailbreak state. (Tether boot instructions can be found below)
- Dev-Team: For the convenience of kernel hackers like @comex and @i0n1c, we have a new redsn0w 0.9.8b3 that supports a TETHERED jailbreak for iOS 4.3.4 on all devices that have 4.3.4 except the iPad 2.
- The vast majority of people will want to stay back at 4.3.3 because that’s where the untethered jailbreak is!
- There are no new features in 4.3.4 — only fixes for jailbreak exploits used in JailbreakMe 3.0.
- If you depend on UltraSn0w unlock, avoid Redsn0w, or the stock iOS 4.3.4 firmware.
