Im hoping their able to JB and unlock the new 4.1 that might be comming out today at the apple music event. My GF mistakenly updated my iPhone 4 to the new 4.0.2 firmware sunday and I live in the Bahamas so an unlock is a must for me. At least those of us who cant get their iPhone 4's unlock can say we had an iPod 4 before they launched...lol

I know what has been said about no jailbreak for 4.02 but can anyone please explain why it is not possible to downgrade an iPhone 4 with 4.02 to 4.0 and the jailbreak it with redsn0w

You cant downgrade because apple signs all of you restores. Notice when your restoring your iPhone it says at one point contacting apple servers. Well they are only right now signing for restores on the new firmware.
An exploit hasnt been found yet to jailbreak the iPhone 4 without using the PDF exploit which apple fixed in 4.0.2...

4.01 and 4.02 were minimal upgrades. 4.1 is the biggie IMHO

OK My new iphone 4 didn't get here before apple plugged the JB (came with 4.0.2), it is going to replace another JB phone I have (which will go to my wife). My current thinking is to let new phone sit on the shelf until a 4.1 JB is ready. I need JB as I make use of MyWi to connect my iPad3g (ATT rates ridiculous- tried the $15/250) to it. So my question is do I have to activate my new phone now to use umbrella to save off the shsh blobs in order to be able to JB when 4.1 JB comes out ?I don't drink kool-Aid, I don't join cults.
This is why I break out in cold sweat going to Apple retail store.

There is no way to downgrade without SHSH but:
Update #2: Finally got to the bottom of this, thanks to Saurik who clarified it for me. It seems that more shsh are on file and even some of you that havent ever jailbroken and just got a new iphone may actually have an shsh on file. Itís definitely worth a try to set up Saurikís signature server in your hosts file and try to restore that way. You may get lucky and get a downgrade even on a new device.

You can most def downgrade from 4.0.2.. I had to upgrade my brother in laws phone because it was bricked, then just pointed the servers to sauriks, and it downgraded to 4.0.1 within minutes

If you pointed your hosts to Saurik's server then he had your SHSH on file!He who asks a question looks foolish for 5 minutes. He who doesn't ask a question remains foolish forever.

I am not sure if I have "successfully" downgraded, but I am now at the iTunes+USB screen and Tiny Umbrella says I am at 4.0 version. I am willing to believe it
Now I am waiting for the Phonebook sim I ordered online to activate the iPhone and get in to it, to jailbreak and unlock using jailbreakme.com
For the record, I did not save my SHSH blobs on Saurik's server. All this talk about "..well you had the blobs on file" is pointless, because clearly in some cases the blobs are there on Saurik's server, perhaps without any intervention. So this is definately no. 1 in the list of things to do if you wish to downgrade.
