Thursday: RIM announces that it sold 1 million BlackBerry 10 phones in the quarter that ended March 2, above the 915,000 that analysts were expecting. Details on U.S. sales are not part of the results because the Z10 became available there after the quarter ended. But RIM lost about 3 million subscribers to end the quarter with 76 million. It's the second consecutive quarterly decline for RIM, whose subscriber based peaked at 80 million last summer.
