Unlock iPhone 4, 3GS iOS 4.3.2 Using Ultrasn0w 1.2.2

The Dev Team have released an update to Ultrasn0w unlock fixing the incompatibility issue with 4.3.2. Ultrasn0w 1.2.2 can now unlock iPhone 4 and iPhone 3GS on supported basebands. The earlier version, Ultrasn0w 1.2.1 brought compatibility to iOS 4.3.1.

Note: Ultrasn0w 1.2.2 can unlock iPhone 4 on baseband 1.59.00 and iPhone 3GS on basebands 04.26.08, 05.11..07, 05.12.01, 05.13.04 and 06.15.00. It cannot unlock the new basebands 2.10.04, 3.10.01, or 4.10.01.

Before you go ahead with the unlock, you can jailbreak iOS 4.3.2 untethered while preserving your unlock baseband using either Sn0wbreeze 2.6 or PwnageTool 4.3.2. Instructions to jailbreak using Sn0wbreeze 2.6 are given here.

After jailbreaking, do the following:

1. In Cydia go to the ‘Manage’ tab.

2. Tap ‘Sources’, then tap ‘Edit’.

3. Tap ‘Add’ and enter http://repo666.ultrasn0w.com. Tap ‘Add Source’.


4. Let Cydia update it’s sources. Once this is done, search for ‘ultrasn0w 1.2.2’ in Cydia and install it.


5. After installation, reboot your iPhone using the normal โ€œslide to power offโ€ swipe.

That’s it. Your iPhone will be automatically unlocked.

    Guys, I think gevey sim is quite nice, I am using it with baseband 02.10.04. Don’t see any problem on it!

    This was damn frustrating for me too, but the time I put Gevey in my iPhone, I stopped reading these news. I know this so called DevTeam is pasing time only, they are getting money not to release the unlock uptill Apple announce the the release date for iPhone5.

    Don’t be surprised this is gonna happen, but when… that Apple only knows.

    Guys, I am on Gevey SIM, it works so perfectly, no need to jailbreak your phone, it simple to use, I have updated my iOs to 4.3.2 (the latest) y’day, GEVEY ROCKS….. It works in India, I am sure as I am using it with Idea (Maharashtra/Andhra pradesh).

    I spent 3K in India, and damn sure that it worth spending rather than waiting for unlock.

    So think and start using Gevey.

    Any query on Gevey SIM u can contact me on – 09912743888. (Please note: I am not a seller, I can just guide)
    I would be happy to giude u in case u wish to see ur more valuable iPhone works.

    @Ravi: I think I’m just gonna go with Gevey SIM.

  6. ravi says:

    @tony: thanks ๐Ÿ™‚ but Gevey really do work great.

    Guys, it works even on Wi-Fi face time and 3G, tested and confirmed!!!

    No need to worry about iOs updation … it still works smoothly.

    Only the thing is when u switched of, u need to follow the process (112 and all) to activate it. But it hardly takes a min.
