Show your smartphone some love for Valentine’s Day and think pink. Otterbox wants you to trade the traditional chocolate and roses for something that will outlast the holiday. The company is offering protective Commuter Series Strength cases that benefit the Avon Breast Cancer Crusade.

“OtterBox’s sponsorship of the Crusade and Avon Walk for the past two years has enabled us to support organizations nationwide that are making great strides in breast cancer research and care,” says Carol Kurzig, president of the Avon Foundation for Women. “There is still much more work to do to end breast cancer, which is why we are so appreciative of supporters like OtterBox that are helping us work towards creating a world without breast cancer. We are proud to once again have OtterBox as an official Avon Walk for Breast Cancer sponsor during the Avon Walk’s 10th birthday season and the 20th anniversary of the Avon Breast Cancer Crusade.”

In the fourth quarter alone, OtterBox donated more than US$317,000 from the sale of the Commuter Series Strength cases, a marked increase over the $179,000 donated during the entire year previous. Ten percent of the purchase price directly supports the cause.

The Strength line features pink-and-white Commuter Series cases for the Apple iPhone 4/4S, HTC EVO 3D and BlackBerry Torch II; as well as two limited edition graphic cases for the iPhone 4/4S. For more info go to http://www.otterbox.com/strength .
