UPDATED with 18.104.22.168
The iPhone Dev Team has updated PwnageTool to version 4.3.3 to support untethered jailbreak on iOS 4.3.3 using i0n1c’s exploit. All devices (except iPad 2) are supported. This includes iPhone 4, 3GS, iPad 1, iPod touch 4G/3G and Apple TV.
Why use PwnageTool over Redsn0w? Its simple. If your iPhone relies on a carrier unlock, you must use PwnageTool 4.3.3 to update to a custom iOS 4.3.3 firmware without the upgraded baseband so that you can unlock using Ultrasn0w.
- Download iOS 4.3.3 firmware for iPhone, iPad, iPod touch or Apple TV.
- Download and install the latest version of iTunes.
- Download PwnageTool 22.214.171.124 for Mac OS X.
