>>1735326I understand your problem with the "two lockscreens", kinda bothers me too. But I really worry about security so I made a 'visual' workaround. I set the same wallpaper on both widgetlocker and the stock lockscreen (with the PIN). Them I simply use the "fade" or "zoom in" effect of widgetlocker.
With this, unlocking the phone gives the impression that your access is barred by the stock PIN. I wish I could make a webm for you but it's impossible for me with my current android version and I also not rooted.
In my current set-up, I unlock by draging the clock hand down which brings the stock lockscreen with the PIN (and the same wallpaper, but inverted), giving the impression of its hand actually going down.
