A little after Apple released iOS 4.3.3 earlier today, we got the confirmation that the company hadn’t patched i0n1c’s untethered jailbreak exploit. That’s good news for jailbreakers who will most likely get updated jailbreak tools from the Dev Team shortly.
In the meanwhile, if you can’t wait for an officially updated jailbreak, you can still run the latest version of RedSn0w over your iPhone 4.3.3. It will be a tethered jailbreak but that will get you going until RedSn0w, PwnageTool, or Sn0wBreeze get an update…
Now I only tested this on my iPhone 3GS, but I hear it also works for iPhone 4, iPod Touch 4G, and iPod Touch 3G.
Step 1: Update your iPhone to iOS 4.3.3. Note that if you are unlocked and want to keep your unlock, do not update to 4.3.3. Instead, wait for a PwnageTool update.
Step 2: Jailbreak your iPhone using our RedSn0w tutorial, and the latest version of RedSn0w available from our download section. Follow the instructions from our guide and make sure you point RedSn0w to iOS 4.3.2.
When you’re done, your iPhone will reboot. From now on, you will have to use RedSn0w to boot tethered every time you reboot.
If you don’t want to deal with all that stuff, I think the best option is still to wait for an official updated jailbreak, which should just be a matter of days.
