Research In Motion and AT&T finally put the much-delayed BlackBerry Bold on store shelves Tuesday. The device, aimed at corporate and business users, offers international wireless coverage with global 3G capabilities, built-in GPS, WiFi and access to thousands of services and applications available from AT&T’s consumer and business application developers. The phone, exclusively available through AT&T, had been held up for undisclosed reasons for several months following its initial unveiling in May.
