Verizon Wireless will become the first company to sell Motorola’s slim Q, a phone with a miniature keyboard, the companies said Monday. The Moto Q phone, which runs on Microsoft software and will go on sale May 31, will compete with Research In Motion’s BlackBerry wireless email device. The Q is a high-end phone, something of a cross between a BlackBerry and a video iPod, that Motorola will try to pitch to corporations as well as consumers.
