SAN FRANCISCO (AP) - BlackBerry smartphone maker Research In Motion Ltd. says it recalled about 1,000 of its BlackBerry PlayBook tablet computers due to defective operating software that can make it impossible for users to set up the device.
    
The Waterloo, Ont.-based gadget maker said in a statement Monday that only PlayBooks with 16 gigabytes of memory were affected and the majority of them had been shipped to stores but not yet sold to customers.
    
RIM said it is working to replace the affected tablets and that customers that did end up with an affected tablet can contact RIM for help.
