has anyone else had this and gotten it resolved? i'm having the same issue using widgetlocker and a pin unlock thats required by school for exchange access. before the jb update i was able to set it to not lock the phone for ~15 minutes after it timed out, and it would just give me my normal widgetlocker lock screen. if i hit the home button to either turn the screen on, or from the lock screen, nothing would happen. once it was off for the 15 minutes the pin would be required once i got past the widgetlocker screen.
now a press of the home button will take me straight to my launcher even if the screen was off as long as the timer for the pin requirement hasnt gone off.
Hey, the only thing that seems to fix it is enabling S Voice and checking the "open via the home key" box. I'm not willing to deal with the home key lag in that case, though.
