How to Downgrade iPhone 4 Baseband 4.11.08 to Any Unlockable Baseband?

Hello! I have accidentally restored my iPhone 4 to iOS 5.0.1 and now my iPhone is in locked state. I’ve managed to downgrade my iPhone from iOS 5.0.1 back to iOS 4.2.1 using saved SHSH blobs but the problem is my baseband is still 04.11.08 ;( Can anybody help me to downgrade it to any unlockable baseband so that I could unlock with Gevey SIM? Help me out please! Thanks.

Hello Mike! Sad to say, but downgrading iPhone 4’s baseband is not yet possible at the moment. Hopefully the iPhone Dev-Team will come up with a tool that will allow users to downgrade baseband of the iPhone so that they could unlock their iDevice from its contracted mobile phone carrier.

At the moment, the only thing you can do is to wait like everybody else is doing. Hopefully, the Gevey SIM maker will release the new Gevey SIM for iOS 5 4.11.08 baseband as soon as possible.

On the other hand, if you haven’t jailbroken your iPhone on iOS 4.2.1, you can refer on our step-by-step guide on how to jailbreak iOS 4.2.1 using Greenpois0n jailbreak tool (which is available for both Mac OS X and Windows users). Just download Greenpois0n RC6.1 using this link, and then jump on to this blog post on how to jailbreak iOS 4.2.1 using Greenpois0n. That’s it! Good luck.
