The Qwell app, when enabled, puts your 'Berry on silent. Callers hear a taped message that inquires if the call is an emergency. If the answer is "no", the caller can leave a message for your voice mail, or the caller can press "9" and have the call sent through to your phone for you to take. It is like having a receptionist without having to pay for one and giving time off for her to attend her cousin's wedding. A Pro version that allows you to make your own outgoing message is in the works.
Even better, Qwell is now running a contest. For every 1,000 Facebook likes and 1,000 Twitter followers, they will give away a BlackBerry Torch 9800. You can visit Qwell's Facebook page by clicking here, and you can follow Qwell on Twitter at @qwellyourphone.
