BlackBerry

BlackBerry is a line of mobile e-mail and smartphone devices developed and designed by Canadian company Research In Motion (RIM) since 1999.

BlackBerry phones function as a personal digital assistants and portal media player. BlackBerry phones are primarily known for their ability to send and receive (push). Internet e-mail wherever mobile network service coverage is present, or through Wi-Fi connectivity. BlackBerry phones support a large array of instant messaging features, including BlackBerry Messanger.

BlackBerry commands a 14.8% share of worldwide smartphone sales, making it the fifth most popular device manufacturer after Nokia,Samsung,LG and Apple. The consumer BlackBerry Internet Service is available in 91 countries worldwide on over 500 mobile service operators using various mobile technologies.

Modern GSM-based BlackBerry handhelds incorporate an ARM 7, 9 or ARM 11 processor, while older BlackBerry 950 and 957 handhelds used Mudit 80386 processors. The latest GSM BlackBerry models (9100, 9300 and 9700 series) have an Intel PXA930 624 MHz processor, 256 MB (or 4 GB in the Torch 9800) flash memory and 265 MB SDRAM. CDMA BlackBerry smartphones are based on Qualcomm MSM6x00 chipsets which also include the ARM 9-based processor and GSM 900/1800 roaming (as the case with the 8830 and 9500) and include up to 256MB flash memory. The CDMA Bold 9650 is the first to have 512MB flash memory for applications. All BlackBerrys being made as of 2011 support up to 32 GB microSD cards.

The first BlackBerry device, the 850, was introduced in 1999 as a two-way pager in Munich, Germany. In 2002, the more commonly known smartphone BlackBerry was released, which supports push e-mail, mobile telephone, text messaging, Internet faxing, Web browsing and other wireless information services. It is an example of a convergent device. The original BlackBerry devices, the RIM 850 and 857, used the DataTac network.

BlackBerry first made headway in the marketplace by concentrating on e-mail. RIM currently offers BlackBerry e-mail service to non-BlackBerry devices, such as the Palm treo, through its BlackBerry Connect software.

The original BlackBerry device had a monochrome display, but all current models have color displays. All models except for the Storm, series had a built-in QWERTY keyboard, optimized for "thumbling", the use of only the thumbs to type. The Storm 1 and Storm 2 include a SURE TYPE keypad for typing. Originally, system navigation was achieved with the use of a scroll wheel mounted on the right side of phones prior to the 8700. The trackwheel was replaced by the trackball with the introduction of the Pearl series which allowed for 4 way scrolling. The trackball was replaced by the optical trackpad with the introduction of the Curve 8500 series. Models made to use iDEN networks such as NEXTEL and Mike also incorporate a push-to-talk (PTT) feature, similar to a two-way-radio.

Operating System

The operating system used by BlackBerry devices is a proprietary multitasking environment developed by RIM. The operating system is designed for use of input devices such as the track wheel, track ball, and track pad. The OS provides support for Java MIDP 1.0 and WAP 1.2. Previous versions allowed wireless synchronization with Microsoft Exchange Server e-mail and calendar, as well as with Lotus Domino e-mail. The current OS 5.0 provides a subset of MIDP 2.0, and allows complete wireless activation and synchronization with Exchange e-mail, calendar, tasks, notes and contacts.,

Third-party developers can write software using these APIs, and proprietary BlackBerry APIs as well. Any application that makes use of certain restricted functionality must be digitally signed so that it can be associated to a developer account at RIM. This signing procedure guarantees the authorship of an application but does not guarantee the quality or security of the code. RIM provides tools for developing applications and themes for BlackBerry. Applications and themes can be loaded onto BlackBerry devices through BlackBerry App World, Over The Air (OTA) through the BlackBerry mobile browser, or through BlackBerry Desktop Manager.

CPU

Early BlackBerry devices used Intel 80386-based processors. BlackBerry 8000 series smartphones, such as the 8700 and the Pearl, are based on the 312 MHz ARM XScale ARMv5TE PXA900. An exception to this is the BlackBerry 8707 which is based on the 80 MHz Qualcomm 3250 chipset; this was due to the PXA900 chipset not supporting 3G networks. The 80 MHz processor in the BlackBerry 8707 meant the device was often slower to download and render web pages over 3G than the 8700 was over EDGE networks. In May 2008 RIM introduced the BlackBerry 9000 series which are equipped with XScale 624 MHz processors. The BlackBerry Curve 8520 features a 512 MHz processor, while the Bold 9700 features a newer version of the Bold 9000's processor, but is clocked at the same speed
