Downgrading iPhone 4 using iPhone 3gs SHSH blobs?

[aido2261]

I was just wondering if it was possible to downgrade an iPhone 4th Gen (iOS 4.0.2 never jailbroken) using the SHSH blobs from my old iPhone 3GS (iOS 3.1.3 jailbroken) saved on cydia?

If someone could give me a step by step guide to doing this ud be doing me a hell of a favour.

If its not possible to do, is there a way of jailbreaking the iPhone 4 iOS 4.0.2? from what ive found there isnt so help is appreciated!

Thanks heaps

You cant do that, sorry.

You also cant jb 4.0.2 on an iP4.

I knew thered be a few posts the same, but hearing it yourself makes it hurt less haha.

Also, ive been reading thet most likely wont bother jailbreaking 4.0.2 and just wait for Apple to finish with 4.1 beta. Is that true to?

If i knew how to jailbreak id do it myself, but unfortunately im not that smart haha
