The company had posted a net income of $911 million for the three months ended November 27, 2010, Research In Motion said.
RIM attributed the substantial decline in net income to the widespread internet services outage in October, which hit BlackBerry users across the world, besides the previously announced charge on its unused PlayBook inventory.
"The company experienced a service interruption which resulted in the loss of service revenue and the payment of service credits in the quarter totalling approximately $54 million, related to the interruption in the availability of the company's network," RIM said.
The BlackBerry-maker has also reported lower-than-expected revenues of $5.2 billion in the quarter under review, down 5.45 per cent from the same period last year.
RIM had projected a revenue between $5.3 billion and $5.6 billion for the period.
Looking ahead, the company expects revenues in the fourth quarter of the 2012 fiscal, ending March 3, 2012, to be in the range of $4.6-4.9
