Before I set up a pattern to lock the phone, do you still have to swipe the green un-lock arrow and then enter your pattern? making it a 2 step process.
I finally put a pattern on my phone the other day. I hesitated for a couple of months because I thought it would slow me down when I answered phone calls. I was pleased to find that it really doesn't take any time at all to swipe the pattern. I feel a lot better with it on there (I know it's not perfect, but it's better than nothing). Hopefully they will a couple of the security glitches with the next update.
@soyboy, I had the pattern for awhile when i first got the phone, you get really good/fast at it. It was when i kept putting my phone to sleep only someone to text me 5 seconds later i kept having to do the pattern.
