I've got an iPad 2which came with 4.3.5 out of the box. I've also got an ipad 1, but I'm only running 4.2.1 on that one. There hasn't been a reason for me to upgrade beyond that as far as I can tell. Anyway, I used iFaith to dump the shsh blobs and then compile a signed version of 4.2.1, but the problem is that apparently that version isn't compatible with the ipad 2. so what I'm wondering is if someone with 4.3.3 could dump their blobs and send the file over to me so I can build a signed IPSW with someone else's blobs. Is that possible? If so then it would solve the problem of not being able to downgrade from 4.3.5 when that is all you have ever had.
