Jailbreak iPhone 4 4.3.2 Untethered And Preserve Baseband For Unlock with PwnageTool 4.3.2 [Tutorial]
The iPhone Dev Team has updated PwnageTool to version 4.3.2 to support untethered jailbreak on iOS 4.3.2 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 carrierunlock, you must use PwnageTool 4.3.2 to update to a custom iOS 4.3.2 firmware without the upgraded baseband so that you can unlock using Ultrasn0w. Windows users should alternatively use Sn0wbreeze 2.6, instructions for which can be found here.
Complete step by step instructions for jailbreaking using Redsn0w on both Windows and Mac can be found here.
