Yes it's pattern lock .. but no, not that pattern lock. Pattern Lock Pro is a locking app of the same name (add the pro of course) that simply lets you use a pattern of your choosing to unlock your device. The settings screen is simple, letting you choose your pattern, lock timeout and apps to override. I'm a big fan of pattern locking on touchscreen devices, as it gives a quick one-handed simplicity to things. Pattern Lock Pro comes in handy for just that, however I do wish it was a bit more responsive. It seems to hang a bit as you map out your pattern, but hopefully something that can be fixed down the line. Check out the video above for my review, then head to BlackBerry App World for more.
