RBC Capital says it's seeing encouraging signs regarding the sales of BlackBerry's software to regulated sectors, including government ,financials, and healthcare. The firm says that the company's mobile device management system, BES 12, is adding customers, while its resellers are getting more comfortable selling its software and sales of its technology solutions products are beating its guidance. RBC slashed its hardware sales estimates for the company and expects its Q1 revenue to come in well below expectations as a result, but adds that software has become the company's focus. It keeps an $11 price target and Sector Perform rating on the shares.
