2002 - BlackBerry Adds Voice Calls
The BlackBerry 5810 integrated the popular BlackBerry email solution into a phone with messaging, calendar and other business features. It was the first of its kind with GSM/GRPS capabilities. However, despite the ability to make phone calls, it did not yet include a microphone so all calls had to be made through an external headset. For a hefty $749 price tag, users could cut down from two devices, an email device and a cell phone, to just one device -- a revolution at the time.
