Is there anyway to change the background on the lock screen?

[Viper786]

I have a 4 digit lock code on my phone that needs to be entered in order to use the phone. The background on this is different from the background I have in my TF3D tabs. I tried the cab that uses the same background for all tabs, but it doesn't use the same background for the lock screen. Anyone know how to change that?

Thanks!
