From 4.11.08 to 4.10.01 BB, is it possible?

Hello,
I found this this tutorial, to downgrade from 4.11.08 baseband to 4.10.01, is it really working?
The only problem is that I can not download 4.3.5 ios from apple, although I can download it from Felixbruns.de

No, you won't be able to. This is true when Apple release OS5 while they were still signed 4.3.5. Since then, they no longer sign this fw and therefore, you can't.

But I can download old version of iTunes and 4.3.5 ios?
And sorry, but what does mean ''they no longer sign''?

No, there's nothing you can do to downgrade that baseband.
You're too late, it could only be done when Apple was still signing 4.3.5.
