How do I jailbreak my iPhone 4 on iOS 4.3.4 / 4.3.5?

If you have saved SHSH[1] for 4.3.3, then it is recommended that you downgrade[2]. If you haven't saved SHSH[1] or you still want to jailbreak 4.3.4 or 4.3.5, then you can use redsn0w[3], but please note that this is a tethered[4] jailbreak.


  1. What is a SHSH blob?
  2. How do I downgrade the firmware?
  3. Where do I download redsn0w?
  4. What is tethered / untethered / semi-tethered?
