Using it. Nice. It seems to be just one more layer of security, if I ever needed it.
Most of you staying with 4 nodes, or have you gone crazy with your patterns?
I tried to make a 7-node pattern, but after 5 nodes, it would unlock. I think 5 is the max.... Try it with a longer one and then just get up to the 5th one and it'll unlock the phone...at least that was my experience.
