[Galaxy S III Android Development] Scarface1991:
Yes it is the AOSP Lock and the quick app shortcuts all stay the same.

I think the position of the Lock can be edited inside the "keyguard_screen_tab_unlock" file inside framework-res.apk I will have a look at this later on.

I used this code for this to work:

I haven`t written the additional code by myself. It was more of a decompile - copy and paste - recompile job
