Most BlackBerry devices have a full keyboard. The Pearl uses a modified QWERTY layout on a 4-row, 5-column keypad, with a proprietary predictive input algorithm called SureType. The Pearl supports the full range of BlackBerry  enterprise functionality.

Unlike other BlackBerry devices, the Pearl includes a music player, camera, as well as other multimedia functions. It requires the purchase of a MicroSD memory card to support storage of multimedia files beyond the 64MB provided internally.

Most notable, the Pearl uses a translucent trackball called the "Pearl", which facilitates horizontal and vertical scrolling, instead of the traditional BlackBerry scroll wheel. The backlit color of the 8100 trackball is controlled by a series of LEDs and may be changed by software loaded on the phone; the 8110, 8120 and 8130 models trackball is lit only in white. The color customization capabilities also extend to the notification LED in the top right corner of the device. This LED can be programmed to blink different colors depending on which contact has called, texted or emailed

The BlackBerry Pearl is aimed towards both business users and consumers. Its advertising campaign features several people including Mariska Hargitay and Douglas Coupland.

The BlackBerry Pearl provides Quad-Band network support on 850/900/1800/1900 MHz GSM/GPRS and EDGE networks to allow for international roaming between North America, Europe and Asia Pacific. The BlackBerry 8130 includes EV-DO high speed CDMA data capabilities and the BlackBerry 8120 is the first Pearl model to support Wi-Fi.

BlackBerry Pearl 8110, 8120 and 8130 use the Antioch chip from Cypress Semiconductor, a Westbridge peripheral controller enabling "direct connection between peripherals, creating ultra-fast transfers". This upgrade from 8100 provides faster USB sideloading than older phones, and fast connection to the microSDHC card, capable of transferring 1GB file in less than 70 seconds - over 16Mbyte/s transfer rate. This speed significantly surpasses that of the earlier iPhone, Motorola RAZR or Sony Ericsson Walkman. In mid 2010, the Pearl 81xx will have a successor with 3g capabilities- 9100.

The BlackBerry Pearl 8220, formerly known as the BlackBerry KickStart, is RIM's first flip phone. It is thus often referred to as the "Pearl Flip" or "BlackBerry Flip".

The Pearl Flip is available in the United States through U.S. Cellular , T-Mobile , Verizon and Cellular South and in the UK through O2, in Indonesia through Indosat, and in Canada through Rogers, Telus, and Bell Mobility. The phone has been known by many names, from the original codename BlackBerry "Kickstart" name to the current BlackBerry Pearl 8220 Smartphone name. A CDMA version is available for Verizon and Alltel known as the 8230.

The Pearl Flip is very similar to the original Pearl and uses the same predictive text input that the Pearl uses. It has a 2.0 Megapixel camera and video recording. It is the first BlackBerry to feature Wi-Fi and mobile calling in a new flip design.
