How to Jailbreak iOS 4.3.1 with PwnageTool 4.3 (Untethered)

PwnageTool 4.3 is out to jailbreak iOS 4.3.1 on iPhone 4, 3GS, iPod Touch 4G, 3G and iPad 1. These are the steps to jailbreak iOS 4.3.1 untethered. PwnageTool will create a custom firmware 4.3.1 to jailbreak iPhone, iPad, iPod Touch and Apple TV 2G. PwnageTool also preserves iPhone baseband.

In this guide you’ll learn how to create custom iOS 4.3.1 to jailbreak iPhone 4, 3GS (New & Old bootrom), iPod Touch 4G, 3G, iPad and Apple TV 2G while preserving iPhone baseband so that you may use UltraSn0w to unlock iPhone later.

If you do not depend on UltraSn0w unlock, RedSn0w is much easier and faster way to go for. RedSn0w guides are linked at bottom.

NOTE: PwnageTool is available for Mac OS only. Windows users can use Sn0wbreeze (Guides linked at bottom) to create custom firmware 4.3.1. iPad 2 sport is missing in all jailbreak tools.

Andrés April 4, 2011, 11:28 pm

iPhone 4 baseband 1.59.00 is unlockeable with Pwnage 4.3 ?????? And Ultrasn0w 1.2 ???

SenseiPhone April 21, 2011, 9:13 am

No. But instead, update to 4.3.1 with TinyUmbrella to prevent baseband, jailbreak with redsn0w, unlock using ultrasn0w.

sikvdila April 5, 2011, 12:56 am
