Jailbreak Your iOS 4.0 With Pwnage Tool 4.0

Apple released the firmware 4.0 for the iPhone and iPod Touch devices yesterday (Monday, June 21st) which was a major upgrade for the devices. As mentioned in our post before, you shouldn't upgrade your devices if you have relied on tools for hacktivation and/or a carrier unlock. Today, the iPhone Dev Team has released the PwnageTool 4.0.

Important

Please read through everything carefully as there are upgrade traps and different upgrade scenarios that need to be fully understood and considered before using the new tool.

With PwnageTool 4.0, there are certain devices that aren't supported at all because these devices are not supported by the iOS 4.0 software. The Dev Team is currently working to get past these restrictions. Currently the devices that are NOT supported are the following:

• iPhone 2G


• iPod Touch


• iPod Touch 3G

The PwnageTool 4.0 also only recognizes the official IPSWs that were released yesterday (Monday, June 21st). If you had developer access to the 4.0 GM IPSWs, DO NOT use those.

iPhone 3GS

Summary: Currently, PwnageTool only works on previously jailbroken 3GS devices with the old bootrom.

• If you have a Jailbroken iPhone 3GS with the OLD BOOTROM and you DID NOT use Spirit to jailbreak then you can create the ipsw with PwnageTool 4.0 and restore with your jailbroken recovery mode.


• If you have an iPhone 3GS with the NEW BOOTROM this is NOT supported by PwnageTool 4.0

iPhone 3G

• If you have a Jailbroken iPhone 3G at 3.1.2 (but not jailbroken with Spirit) then you should create the ipsw with PwnageTool 4.0 and restore from recovery mode or DFU mode.


• If you have an out of the box iPhone 3G you should restore using a PwnageTool 4.0 ipsw using DFU mode.


• If you have a Jailbroken 3.1.3 iPhone 3G it is very possible that this can fail from recovery mode, if this failure happens you will need to restore using DFU mode.


• As an alternative to PwnageTool, you can use redsn0w on iPhone 3G (on both Windows and Mac) as mentioned in our last post.

IMPORTANT! Whenever you need to enter DFU mode, you will need to do so using PwnageTool.

iPhone 2G

• If you have an iPod touch 2G (non-MC model) that is jailbroken (but not with Spirit) then you can restore using recovery mode.


• As an alternative to PwnageTool, you can use redsn0w on non-MC iPod Touch 2G (on both Windows and Mac) as mentioned in our last post.

Unlocking

Ultrasn0w has been updated to unlock the iOS 4.0 firmware across any iPhone and was released yesterday. Our download link and post can be found here for instructions how to get it up and working. As for anything regarding jailbreaking/unlocking, be wary of upgrading and don't jump the gun if you rely on using jailbreak and unlock features.
