Blame it on more carriers and better deals. RIM is glowing in the fact that its Curve, still a well-received phone even without the press of the iPhone, managed to beat the iPhone in 1st quarter sales. Part of it was Verizon, who offered help in the form of a buy-one-get-one-free sale for Blackberries. So, not only is the Curve at the top of the handheld market, but two other Blackberry phones grace the top five. Not a bad racket. source
