Will still be tricky. Baseband downgrade is tricky and risky  

But if it was jail broken before, it maybe possible to downgrade to the iOS it was jailbroken in using Saurik's signing server. Cydia has been saving the SHSH blogs. 

I can look at it and advise.

Pity, you may have a brick, or sell it to someone going to the States and wants to be on AT&T - but still we can try :-)

Sawa, Okech. I will find you, with the paperweight:-)

I hear these guys never backed up that SHSH....

Yes, its possible, only if the iOS is compatible with the device, and you have saved SHSH using Tiny Umbrella - The SHSH must actually been saved before upgrading, so if you had no idea, then you never save them, unless maybe Cydia saved them for you. Anyway, I can help you by looking at the phone and see if I can help - you know how to find me :-)

Wash,

Jailbreaking alone does not unlock the phone, but just makes it possible t install UltraSn0w that unlock the phone.

In your friend's case, he maybe be in some trouble. The baseband (think of it as the modem that does the actual network connectivity) that comes with iOS 5.0.1 is not unlockable, not now for sure.

Was the iPhone 4 bought contract from AT&T? If so, even AT&T will not unlock it.

There is an expensive solution called Garvey SIM, which is hardware based, but at least it will work.



Hello Philip,

The phone is jailbroken, but it's the Baseband which is locked. Not sure this statement makes sense. My understanding is that we need to unlock the baseband. Something like changing the baseband from 04.11.08 to 04.10.01 or lower....

Alternatively, I think I need to downgrade from firmware 5.0.1 to 4.3.5, but there is this fear that Apple will not "sign it" - whatever that means.

Is it possible to downgrade to some earlier firmware and get the phone working?
