Can you use the SHGH from 3.1.3 Iphone 3gs to downgrade iphone 4 4.0.1?

So guys, Hello!

I recently upgraded my iphone 3gs 3.1.3 to get an iphone4 with 4.0.2 last week. I did not know that there was no jail break for it when i did. I am actually addicted to any jail broken phone and now i just hate my new phone! anyway, so i no longer have the 3gs but i did the "make my life easier" thingy in Cydia and I was wondering if I can use the SHSH Blobs from my 3gs to downgrade my iphone 4 4.0.2 to something lower so that i can jail break it?

I hope you guys can understand what i said up there

No you can't, they are device specific, sorry

Frig! so there is no way AT ALL, that i can downgrade my iphone 4?
ok, when u say device specific, you mean by serial number? because i have a couple friends with iphone 4s that are 4.0.1 and they are jail broken. would i be able to use theirs?

SHSH will only work for the device they are saved for. You are out of luck until a new jailbreak comes out.
