BlackBerry is a line of mobile e-mail and smartphone devices developed and designed byCanadian company Research In Motion (RIM) since 1999.[2][3]
BlackBerry devices are smartphones, designed to function as personal digital assistants,portable media players, internet browsers, gaming devices, and much more. They are primarily known for their ability to send and receive (push) e-mail and instant messages while maintaining a high level of security through on-device message encryption. Blackberry devices support a large variety of instant messaging features, including BlackBerry Messenger.
BlackBerry commands a 11.7% share of worldwide smartphone sales, making it the fourth most popular device manufacturer after Google, Sony Ericsson, and Apple.[4] The consumer BlackBerry Internet Service is available in 91 countries worldwide on over 500 mobile service operators using various mobile technologies.[5] As of October 2011, there were seventy million subscribers worldwide to BlackBerry.[6]
Modern GSM-based BlackBerry handhelds incorporate an ARM 7, 9 or ARM 11 processor,[7] while older BlackBerry 950 and 957 handhelds used Intel 80386 processors. The latest BlackBerry models (Torch 9850/9860, Torch 9810, and Bold 9900/9930) have a 1.2 GHz MSM8255 Snapdragon Processor, 768 MB system memory], and 8 GB of on-board storage.[8][9] All BlackBerrys after OS 5 support up to 32 GB microSD cards.
Operating system
Main article: BlackBerry OS
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. 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, and adds support for Novell GroupWise and Lotus Notes. The Blackberry Curve 9360, Blackberry Torch 9810, Bold 9900/9930, and Torch 9850/9860 feature the most recent Blackberry OS 7 as of October 2011).
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.

BlackBerry Messenger
BlackBerry devices use the proprietary BlackBerry Messenger, also known as BBM, software for sending and receiving encrypted instant messages, voice notes, images and videos via BlackBerry PIN. Some of the features of BBM include groups, bar-code scanning, lists, shared calendars, BBM Music and integration with apps and games using the BBM social platform.
[edit]Third-party software
Third-party software available for use on BlackBerry devices includes full-featured database management systems, which can be used to support customer relationship management clients and other applications that must manage large volumes of potentially complex data.[10]
In March 2011, RIM announced an optional Android player that could play applications developed for the android system would be available for the Blackberry Playbook, RIM's first entry in the tablet market.[11][12][13]
On August 24 2011 Bloomberg News reported unofficial rumors that BlackBerry devices would be able to run Android applications when RIM brings QNX and the Android App Player to BlackBerry.[14][15][16][17] On October 20 2011 RIM officially announced that android applications could run, unmodified, on the blackberry tablet and the newest blackberry phones, using the newest version of its operating system.[18][19]
[edit]CPU
The latest Blackberry devices such as the Bold 9900/9930, Torch 9810, 9860/9860 feature a Qualcomm Snapdragon MSM8260 CPU clocked at 1.2 Ghz. Entry-level models, such as the Curve 9360, feature a Marvell PXA940 clocked at 800 Mhz. Previous Blackberry devices, such as the BlackBerry 9000 series, were equipped with XScale 624 MHz processors.[20] The BlackBerry Curve 8520 featured a 512 MHz processor, while the Bold 9700 featured a newer version of the Bold 9000's processor, but is clocked at the same speed. Early BlackBerry devices, such as the BlackBerry 950, used Intel 80386-based processors.[21][22] 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.
Connectivity
[edit]BlackBerry Enterprise Server
BlackBerry smartphones can be integrated into an organization's e-mail system through a software package called BlackBerry Enterprise Server (BES). Versions of BES are available forMicrosoft Exchange, Lotus Domino and Novell GroupWise. Google has made a Connector for BES which makes BES available for Google Apps as well. While individual users may be able to use a wireless provider's e-mail services without having to install BES themselves, organizations with multiple users usually run BES on their own network. Some third-party companies provide hosted BES solutions. Every BlackBerry has an ID called a BlackBerry PIN, which is used to identify the device to the BES. BlackBerry now provides a free BES software called BES Express (BESX).[23]
BES acts as an e-mail relay for corporate accounts so that users always have access to their e-mail. The software monitors the user's local Inbox, and when a new message comes in, it picks up the message and passes it to RIM's Network Operations Center (NOC). The messages are then relayed to the user's wireless provider, which in turn delivers them to the user's BlackBerry device.
This is called push e-mail, because all new e-mails, contacts, task entries, memopad entries, and calendar entries are pushed out to the BlackBerry device automatically and instantaneously (as opposed to the user synchronizing the data manually or having the device poll the server at intervals). BlackBerry also supports polling email, through third party applications. The messaging system built in to the BlackBerry only understands how to receive messages from a BES or the BIS, these services handle the connections to the user's mail providers. Device storage also enables the mobile user to access all data off-line in areas without wireless service. When the user reconnects to wireless service, the BES sends the latest data.
An included feature in the newer models of the BlackBerry is the ability for it to quickly track your current location through trilateration without the use of GPS, thus saving battery life and time. Trilateration can be used as a quick, less battery intensive way to provide location-aware applications with the co-ordinates of the user. However, the accuracy of BlackBerry trilateration is less than that of GPS due to a number of factors, including cell tower blockage by large buildings, mountains, or distance.
BES also provides handhelds with TCP/IP connectivity accessed through a component called MDS (Mobile Data System) Connection Service.[24] This allows for custom application development using data streams on BlackBerry devices based on the Sun Microsystems Java ME platform.
In addition, BES provides network security, in the form of Triple DES[25] or, more recently, AES[26] encryption[27][28] of all data (both e-mail and MDS traffic) that travels between the BlackBerry handheld and a BlackBerry Enterprise Server.
Most providers offer flat monthly pricing for unlimited data between BlackBerry units and BES. In addition to receiving e-mail, organizations can make intranets or custom internal applications with unmetered traffic.
With more recent versions of the BlackBerry platform, the MDS is no longer a requirement for wireless data access. Starting with OS 3.8 or 4.0, BlackBerry handhelds can access the Internet (i.e. TCP/IP access) without an MDS – formerly only e-mail and WAP access was possible without a BES/MDS. The BES/MDS is still required for secure e-mail, data access, and applications that require WAP from carriers that do not allow WAP access.
