The iPhone 3G fell to second place, as Apple's consumer smart phone market share dropped 10 percent. Two more BlackBerry phones, the Storm and Pearl, held the third and fourth spots, respectively. And the Android-based made an impressive fifth-place showing. Palm, which is expected to later this month, also suffered a 10-percent drop in market share.

Things certainly look rosy for RIM and its popular BlackBerry series. But it's doubtful the Curve, including all the 83xx models, will continue to outsell the iPhone.

The BlackBerry's impressive Q1 sales surge got a huge boost from Verizon Wireless's consumer-friendly "buy-one-get-one" BlackBerry promotion, as well as its heavy marketing of the iPhone-like , which is selling like hotcakes despite tepid and from the tech press.

Verizon certainly won't continue its costly two-for-one giveaway forever, which should result in a slide in Curve sales. As for the relatively new Storm, its popularity will ultimately be determined by consumer word of mouth. If everyday users agree with the pros that the Storm doesn't cut it, sales will fall.
