Unable to Revert back to iOS3

[supercooled]

Hey,

Got a 3G and it's painfully slow on 4 so I'm trying to revert but I aways get some obscure message saying iTunes can't read it... turns out I needed to backup something called SHSH blobs which I learnt about after day late and a dollar short.

Is it still possible to downgrade by any other means?

Please help... it feels like running Snow Leopard on a G3 ... I'm guessing.. no actual experience of such.

Which iOS you're trying to revert to?

I did install iOS 3.1.2 on his 3G last night and he has no SHSH blobs...

I have vers. 3.1.3 off some site that said I needed SHSH Blobs backed up.

Where did you get 3.1.2?

I'm trying another method now... /fingers crossed.

You're using 3G, right? Not 3GS?
If you're using 3G, you can download the 242MB 3.1.2 file here

The 3G doesn't need SHSH blobs for pre 4.0 firmwares. Google the errors you get, they're fixable.

Thanks for confirmation. That's what I thought....
