How can i downgrade my iPad 1 to iOS 4?

Question

I see there are other posts on this where everyone responds saying to Google how.
Well the method to do this with TinyUmbrella only works if you have saved your SHSH blobs before you upgraded. And for the record nothing about downgrading requires jailbreaking. And it's not risky to try whatsoever.
I didn't save my SHSH blobs before only recently upgrading the iOS version, even after learning my lesson with my iPhone 3G when an update to that rendered it so slow it became an expensive paperweight.
Now I have an iPad 1 which is a piece of hardware that will last for many years to come. I don't need another iPad what I need is for the hardware I paid for years ago as an "early adopter" to work as if bloody well should do.
IOS 5 is so laggy it's ridiculous. This I beleive is done intentionally by Apple just to force people to buy more stuff they don't really need. But hey, that's progress, that's what many tech companies do.
But what I want to ask is, if SHSH blobs can be faked?
Surely a developer knows what data is required from the iPad to create SHSH blobs. Since they're unique to each device surely someone who knows enough about Apple firmware and software could fake them and then downgrading would be possible.
So is there anyone here who knows if it can be done and if so how?
If no one on here can help, could I go to an appointment with one of those "geniuses'" in an Apple store and have them do it?
Thanks,
Andrew

It can be a bit annoying that we can't downgrade either iOS like going from 7 to 6 or downgrade any apps, specially if the update app you downloaded is not what you expected. It can be unfair and wrong. Some of us may look at either an iOS or an app, and like it, download it, then later when we do the update, we sometimes find the next version had changed too much and is not what we wanted in the first place.
It is not easy when it comes to iOS, but when it comes to an app, you can have two options, never update if you're really happy with the current version, or update only direct to iPad but don't sync to iTunes. Try out the app and if it is not what you paid for, you can delete it from iPad as long as you have not updated the app in your iTunes library, and sync the earlier version from iTunes back to iPad.
