I've gone through Cydia installed packages and removed everything that I could think of causing this but the "slide to unlock" is still there.
I had the SB settings installed and I thought that might be causing it because you can activate that from almost anywhere but that wasn't it.
I have an iPhone 4 with iOS 4.1 btw
Hope you'll figure this out
Just to check, your iPhone is using 'English' as it's language, right?
