Ultrasn0w has been updated by the Dev Team to include support for unlocking iOS 4.3.2. So if you've been holding off on upgrading and waiting patiently (or impatiently) for an unlock, you can now have your cake and eat it too! As always, you'll need to be running a compatible baseband version (meaning don't upgrade to 4.3.2 via iTunes!) Hit the jump for a walk-through!
What you need
- AT&T/GSM iPhone running a preserved baseband (refer below for compatibility list)
- PwnageTool - download for Mac
- Ultrasn0w (downloaded via Cydia)
Compatible Basebands
- 01.59.00
- 04.26.08
- 05.11.07
- 05.12.01
- 05.13.04
- 06.15.00
Not sure? We have a tip on how to find out what iPhone baseband you're running. Check it out, and if yours is listed, you are okay to move on. If it isn't, please do not attempt an unlock at this time. As you can see in the screen above, mine is not compatible. I have AT&T so I have not been concerned about preserving my baseband.
Jailbreak with PwnageTool
If you have already done this, skip ahead to the next section. If you haven't, you will need to download PwnageTool for Mac as well as the iOS 4.3.2 IPSW file for iPhone 4 or iPhone 3GS{.nofollow}
Make sure you save the IPSW file somewhere you can easily navigate to. I always save mine on my desktop for example.
Then simply follow the instructions on screen to jailbreak via PwnageTool. Once you're done with that and Cydia is installed, you're ready to move on. (Not sure what that is? Check out our how to use Cydia, the Jailbreak store tip.
Unlock your iPhone with Ultrasn0w
First you will need to add the repo for Ultrasn0w. Simply tap Manage and then Sources in Cydia. Tap edit and then the "+" sign to add the Ultrasn0w repository which is http://repo666.ultrasn0w.com
Next search for Ultrasn0w in Cydia under the search tab. Ultrasn0w 1.2.2 should now pop up. Simply install it and reboot your device. You should now have an unlocked iPhone running on iOS 4.3.2!
