Timed Messages - By setting a timer you can control how long messages and pictures you share with contacts can be viewed within BBM. Setting the timer is super easy: Before you send your message or picture, you just tap on the timer icon next to the text bar and choose a length of time you want the recipient to be able to view that message. The message is hidden until the recipient touches and holds on the chat. Then, once the timer has expired (or if the recipient takes their finger off the screen), the message is no longer visible. What I love about the timer is that I can move seamlessly between timed messages and normal messages in a single chat depending on what I'm sending. Oh, and don't get any smart ideas about screen shots…if a screen shot is detected, the sender is notified.
