iPhone downgrade

[kingnev69]

Hiya I'm trying to downgrade a friends iPhone 4 to 4.3.3 without shsh blobs without much success and was wondering if I could use shsh blobs from my 3GS to make the downgrade a little easier?

Thanks for reading

SHSH blobs are unigue to each phone and cant be shared with other phones..
Were the blobs not saved on the iPhone 4?

Yeah not gonna happen without them...Download TinyUmbrella and run that. See what blobs u get. If previously jb'd u might get lucky.
