Updated to correct version number

PwnageTool 4.01 Released http://snapvoip.blogspot.com/
As we all know, on Monday Apple gave a gift to all iPhone, iPod owners, iOS 4. But if you have used PwnageTool to hactivate and carrier unlock, you should not have upgraded. But many people did and they either had no 3G or Edge and some had MMS disappearing.
The Dev Team always advised not to upgrade with Apple upgrades but to waited for the Dev teams release. As per their promise, the Dev Team has released the PwnageTool 4.01.(PwnageTool 4.01).
But their are some caveats and you should watch out. There are some devices that are not supported by the update because Apple does not support these under iOS 4. But as usual, the team is working on a solution for the problem. so as of now;

• iPhone 2G  - not supported
• iPod Touch - not supported
• iPod Touch 3G - not supported

 The new PwnageTool only recognizes the official IPSWs that came out yesterday. The developers had access to IPSW 4.0 GM and those should not be used.

iPhone 3GS

The PwnageTool 4.01 only works with 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 PwnageTool 4.01  (PwnageTool 4.01)

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 4.01 and restore from recovery mode or DFU mode.
If you have an out of the box iPhone 3G you should restore using a PwnageTool 4.01 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.

 iPod touch 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.

Baseband Unlock with Ultrasn0w
ultrasn0w has been updated to cover all basebands from 04.26.08 onward. iPhone 3G and 3GS baseband unlockers (those who rely on ultrasn0w to make phone calls) should always be very wary to update their firmware, however our Ultrasn0w application will unlock all recent (including the current) 3GS and 3G baseband firmware versions.  Once you are jailbroken using PwnageTool 4.01, install ultrasn0w from Cydia and you’ll be unlocked.
The Dev Team thanks @sherif_hashim for finding the crashing command that the new ultrasn0w 0.93 uses! and @oranav (who found the earlier +xlog crash).
