SAN JOSE, Calif.--With BlackBerry OS 10, RIM is redesigning seemingly every aspect of its former operating system,
from the browser to the lock screen. "Peeking" is one design theme. Here, sliding up a thumb or finger from the bottom of the phone slowly dissolves the lock screen, giving you a full or partial view of what's underneath. You can commit and unlock it all the way, or lower the veil once more.
