By the year 2000, RIM established the BlackBerry as the ultimate corporate accessory. However, it still needed to refine some of its technology if it wanted to hold on to that demographic.

That year, it introduced a device with a larger display and bigger form factor: the BlackBerry 957. Its debut also ushered in BlackBerry OS 2.0, whose interface soon became iconic to BlackBerry’s form, as well as the thumb-controlled scroll wheel that BlackBerry devices used for years.

The BlackBerry 5810 debuted two years later in 2002 and was one of the first Java-based BlackBerry devices, as well as the first voice-enabled BlackBerry handset. Unfortunately, you had to plug in an external headset to actually talk on the thing.
