Sales of the BlackBerry Curve 8500 line have been so strong that they're creating shortages, RIM said during a call discussing its latest fiscal results. A disproportionately large number of the 10.5 million BlackBerries shipped were the entry level phone and have left the company struggling to keep up. The shortages are sustained enough that RIM expects a limit to the number of phones it can ship in the spring and warned that its inventory would be "extremely low."
