iOS 4.2.1 Unlock Released With PwnageTool 4.1.3 for iPhone 3G/3GS

The dev team has released a new unlocking tool for the to unlock iPhone 3G and 3GS. PwnageTool 4.1.3 unlocks iPhone devices with baseband later than 05.13.04. The new hack for the AT+XMPP exploit requires users to upgrade to baseband 06.15.00 before attempting an unlock.

PwnageTool 4.1.3 will unlock devices which includes iPhone 3G, iPhone 3GS and the 3G based . However, iPad users will have to download firmware 3.2.2 to upgrade their baseband.

Certainly don’t update to 06.15 if you don’t need to!  Only do this if you need the unlock and you’re stuck on 05.14 or 05.15, and you’re willing to assume the above risks.

An unlock for is not yet available, however, this should be available in the next few weeks. Please note that there is no way to come back down from 06.15, and there’s no hiding the baseband version from Apple.  So this will void your warranty so make your decisions very carefully.

This PwnageTool also contains a 4.2.1 bundle for iPhone3G owners…for all else, it’s still only 4.1.  If you have an iPhone3GS with an old bootrom, the new redsn0w will handle 4.2.1 for you (in fact it covers 4.2.1 for all devices, even though some of them are still tethered at 4.2.1 until @comex can work some untethering magic).  iPhone3GS users with old bootroms who want to go to 4.2.1 should not use this PwnageTool!  Update to stock 4.2.1 first, then use the upcoming redsn0w to update your baseband.

Download PwnageTool 4.1.3 and read all the instructions here. Please note that you will have to jailbreak iPhone in order to use it, you can jailbreak iOS 4.2.1 before you unlock your device.

Currently the unlock is only available for Mac users, but a Windows unlock should be on its way soon.

Jailbreak iOS 4.2.1 with Redsn0w

Yesterday, Apple released the highly anticipated iOS 4.2.1 for the iPod Touch, iPhone and the iPad. The iOS4.2 update is a minor one for the iPod Touch and the iPhone but it brings a bucket load of changes for the iPad. With the iOS 4.2.1 update, the iPad gets AirPlay, AirPrint, Game Center and Multi-tasking etcetera.

Today, the iPhone Dev Team has released an updated version of Redsn0w which is capable of jailbreaking users’ iTouch device running on iOS 4.2. The only downside is that the jailbreak is a tethered one which means that users need to jailbreak their iTouch device again when they restart it. However, for the iPhone 3GS (older boot rom), iPhone 3G and the iPod Touch 2G (Non-MC) this jailbreak is an untethered one.

Here are the steps to jailbreak your iTouch device using Redsn0w 0.9.6b4 :

Step 1: First and foremost, users need to update their iTouch device to iOS 4.2.1 using iTunes 10.1. They also need to download Redsn0w from here. You can also directly download iOS 4.2.1 IPSW.

Step 2: After that, users need to fire up Redsn0w and point it to the iOS 4.2.1 IPSW file. Once the IPSW file has been successfully identified by Redsn0w, users need to click on the Next’ button to proceed.
