iPhone 4 Baseband 4.11.08 Unlock

Perhaps information about iPhone 4 Baseband 4:11:08 this and need. Because it is the current iPhone is one of the items or objects that can not be separated from human life. Let us discuss a little about the matter.

iPhone 4 baseband 4.11.08 Unlock
Apple is still signing iOS 4.3.5, which means you can still downgrade to this iOS version. It has baseband 4.10.01 that can be unlocked with Gevey Blue Turbo SIM.

Here are the steps:

1. Download and install iTunes 10.4 or earlier. You will need to remove iTunes 10.5 first.

2. Download iOS 4.3.5 IPSW for iPhone 4 from Apple.

3. Put your device into DFU mode (search a tutorial on YouTube).

4. Connect to iTunes and it will say that your device is in recovery mode and needs to be restored.

5. Go ahead and click shift+restore (Windows) or option+restore (Mac). Select the IPSW you just downloaded.

6. iTunes will verify with Apple server and begins restoring your device. Once completed you will need the official SIM card to activate it. You can use other tools such as TinyUmbrella to confirm that you now have baseband 4.10.01.

7. Now download custom iOS 5 from here. Reinstall iTunes 10.5 in the meantime.

8. Download latest redsn0w from the Dev Team’s website or from here. Start redsn0w, go to Extras > Pwned DFU. This allows your iPhone to accept custom firmware. If you don’t do this, you will get error 1604, 1600 etc.

9. Connect your iPhone to your computer.

10. Click shift+restore (Windows) or option+restore (Mac) and select the custom iOS 5 IPSW you just downloaded.

This time your baseband will be preserved while running on iOS 5 and you can unlock it with Gevey Blue Turbo SIM.

Again – do it now because once Apple stops signing iOS 4.3.5, you will be stuck forever!
Did you blindly update to iOS 5 without realizing the consequences that it will also update your baseband to 4.11.08 that can’t be unlocked with your Turbo SIM?Apple had stopped signing iOS 4.3.5 on October 17, 2011.

I bought an iPhone 4, it was jailbroken and with gevey sim, so it was working with every carrier.
And one day I attached my iPhone to a PC and updated from iOS 4 to iOS 5, without preserving my previous baseband, so my baseband is now changed to 4.11.08.
Is there any chance again using my phone as phone, not as 'iPhone touch'? And how?

iphone 4 unlocked 4.11.08 baseband. using unlockboot method.

Did it work? Leave your feedback below.
