PwnageTool 4.3.2 will allow iPhone users to safely restore to a pre-jailbroken iOS 4.3.2 firmware and retain their current baseband so that they can use Ultrasn0w to unlock their GSM iPhone, which is only useful for users with older baseband.
Dev Team has provided the following information on their blog:
PwnageTool 4.3.2 now includes the iOS 4.3.2 untether from @i0n1c. (And look, the PwnageTool and iOS version numbers actually match!).
Note that there’s a corresponding update to ultrasn0w, which has been bumped up to v1.2.2 to get along with iOS 4.3.2 (the ultrasn0w update does not include any new baseband support!). Please reboot your iPhone using the normal “slide to power off” swipe after installing ultrasn0w 1.2.2.
PwnageTool 4.3.2 supports the following iOS devices for iOS 4.3.2:
iPad, iPod Touch and iPhone users who don’t care about unlocking are better off using Redsn0w as one doesn’t need to preserve baseband like iPhone users.
Please note that jailbreaking your iDevice may void its warranty so proceed at your own risk. Please don’t forget to backup your iPhone before you proceed. You can refer to this post for instructions on how to backup your iPhone.
PwnageTool 4.3.2 is available only for Mac users and you can download it from one of the mirror sites:
BitTorrent Release – PwnageTool_4.3.2.dmg.6340182.TPB.torrent
Ultrasn0w 1.2.2 can be installed on a jailbroken iPhone 4 (baseband 01.59.00) or iPhone 3GS (baseband 04.26.08, 05.11.07, 05.12.01, 05.13.04 and 06.15.00) on iOS 4.3.1. Note: You can find your iPhone’s baseband by going to Settings –> About –> Modem Firmware
Ultrasn0w 1.2.2 can’t unlock iPhone 4 basebands – 02.10.04 (bundled with iOS 4.1), 03.10.01 (bundled with iOS 4.2.1), 04.10.01 (bundled with iOS 4.3) or iPhone 3GS basebands – 05.14.02 (bundled with iOS 4.1), baseband 05.15.04 (bundled with iOS 4.2.1), baseband 05.16.01 (bundled with iOS 4.3) and baseband 05.16.02 (bundled with iOS 4.3.1, iOS 4.3.2).
iPhone users who don’t care about unlocking but want to fix the signal bar issue also need to install Ultrasn0w 1.2.2.
If you meet the baseband requirements then you can follow these steps to unlock your jailbroken iPhone or fix the signal bar issue (T-Mobile USA users should disable 3G before using Ultrasn0w):
Launch Cydia from the homescreen.
Tap on the Search tab and search for ‘ultrasn0w’. That last “o” is actually the number zero “0”. If you use the letter “o” you’ll get an error.
Select ultrasn0w from the search results.
Then tap on the Install button.
Tap on the Confirm button.
You will be prompted to Restart SpringBoard, tap on it.
Reboot your iPhone, your iPhone should now be successfully unlocked or the signal bar issue should be fixed.
As always, let us know how it goes.
