BlackBerry is all about security, but one thing users commonly ask is how to secure specific applications. With AppLock you can do just that. The $2.99 app lets you lock down emails, SMS, 3rd party apps and more without having to lock your entire device. You can choose specifically what to protect and not have to worry about anyone getting at your stuff. It even has the ability to lock folders on your SD card and comes with an auto-lock so you don't have to think about it.
Contest: We have 50 copies of AppLock to give away. Just leave a comment on this post to enter. Contest ends this Sunday at midnight PDT.
