Really Curious?

I know we can't restore the 4s to 5.0.1 when apple updates iOS but what causes us not to be able to like the iPhone 4. Is it the a5? or another restriction apple has? Just wondering

They stop signing it.

I know that but iPhone 4 users are still able to restore if they have the blobs saved for the phone, what restricts the 4s?
