RIM relies on deep roots with enterprise customers. For years, the BlackBerry was considered more secure and gave it prominence among IT departments. That has made it a hit with government customers. But advances in security software, combined with worker demands for support of iPhones and Android-based devices, have changed things. RIM still wants to court its business customers. At the same time, it wants to expand into consumer markets. So it has created something of a hybrid smartphone appearance that allows people to toggle between business and consumer smartphone appearances and their apps.
