Can i downgrade from 5.0.1 to 5.0?

[L4Leonard]

Is the original 5.0 firmware still being signed by apple, or do i have to use for instance tiny umbrella?

It's not signed by Apple anymore, so you're going to have to find alternative methods.

No. Even with saved SHSH blobs you cannot downgrade. Starting with iOS 5, Apple changed the way the blobs are signed. They are now signed so that they can only be used once.
