I demoed a bunch of phones at Best Buy, and I noticed some had special lock screens like a puzzle or a swipe-up bar. Can you get the swipe-up bar lock screen onto any phone? I'm not sure what phone I saw it on, but I think it was a Droid Incredible 2. It's a bit hard to keep track nowadays, with the sudden explosion of big-screen smartphones. But I do think it was an HTC phone.
