Despite plummeting device sales, BlackBerry (BB -1.43%) continues to hope its device business can see a turnaround. The company even announced a manufacturing agreement with Foxconn at the end of 2013 for the joint development of a consumer smartphone for Indonesia and other fast-growing markets in 2014. Still betting heavily on its device business, BlackBerry investors should hope to see signs of a meaningful consumer brand -- at least among its existing customers. But a leaked employee email revealed by TmoNews suggests there may very little loyalty among BlackBerry's current customers.
