The BlackBerry is a wireless handheld device introduced in 1999 as a two-way pager. 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 as well as a multi-touch interface. It is an example of a convergent device. Developed by the Canadian company Research In Motion (RIM), it delivers information over the wireless data networks of mobile phone service companies. 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 the BlackBerry Connect software. The original BlackBerry device had a monochrome display, but all current models have color displays.
While including PDA applications (address book, calendar, to-do lists, etc.) as well as telephone capabilities on newer models, the BlackBerry is primarily known for its ability to send and receive e-mail wherever it can access a wireless network of certain cellular phone carriers. It has a built-in QWERTY keyboard, optimized for "thumbing", the use of only the thumbs to type. System navigation is primarily accomplished by a scroll ball in the middle of the device (older devices used a track wheel on the side). Some models (currently, those manufactured for use with iDEN networks such as Nextel and Mike) also incorporate a Push-to-Talk (PTT) feature, similar to a two-way radio.
Modern BlackBerry handhelds incorporate an ARM 7 or 9 processor, while older BlackBerry 950 and 957 handhelds used Intel 80386 processors. The latest GSM BlackBerry models (8100, 8300 and 8700 series) have an Intel PXA901 312 MHz processor, 64 MB flash memory and 16 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).
The devices are very popular with some businesses, where they are primarily used to provide e-mail access to roaming employees. To fully integrate the BlackBerry into a company's systems, the installation of BlackBerry Enterprise Server (BES) is required.
On 18 Dec 2008, RIM announced the number of BlackBerry subscribers has reached approximately 21 million.
Operating system
RIM provides a proprietary multi-tasking operating system (OS) for the BlackBerry, which makes heavy use of the device's specialized input devices, particularly the scroll wheel (1995–2006) or more recently the trackball (September 12 2006–Present). The OS provides support for MIDP 1.0 and WAP 1.2. Previous versions allowed wireless synchronization with Microsoft Exchange Server's e-mail and calendar, as well as with Lotus Domino's e-mail. The current OS 4 provides a subset of MIDP 2.0, and allows complete wireless activation and synchronization with Exchange's e-mail, calendar, tasks, notes and contacts, and adds support for Novell GroupWise and Lotus Notes.
Third-party developers can write software using these APIs, proprietary BlackBerry APIs as well, but 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.
CPU
Early BlackBerry devices used Intel-80386-based processors. The latest Blackberry 9000 series is equipped with Intel XScale 624MHz CPU,which makes it the fastest Blackberry to date. Earlier BlackBerry 8000 series smartphones, such as the 8700 and the Pearl, are based on the 312MHz ARM XScale ARMv5TE PXA900. An exception to this is the BlackBerry 8707 which is based on the 80MHz Qualcomm 3250 chipset, this was due to the ARM XScale ARMv5TE PXA900 chipset not supporting 3G networks. The 80MHz Processor in the BlackBerry 8707 actually meant the device was often slower to download and render web pages over 3G than the 8700 was over EDGE networks.
Database
Data extracted from a BlackBerry to a host computer is stored in a single file in a BlackBerry-specific format known as IPD.
Supporting software
BlackBerry handhelds are integrated into an organization's e-mail system through a software package called "BlackBerry Enterprise Server" (BES). Versions of BES are available for Microsoft Exchange, Lotus Domino and Novell GroupWise. 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 BlackBerry PIN, which is used to identify the device to the BES.
BES can act as a sort of 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 and calendar entries are "pushed" out to the BlackBerry device automatically, as opposed to the user synchronizing the data by hand or on a polling basis. Blackberry also supports polling email, which is how it supports POP. Device storage also enables the mobile user to access all data offline in areas without wireless service. As soon as the user connects again, the BES sends the latest data.
An included feature in the newer models of the BlackBerry is the ability for it to track your current location through Trilateration. One can view the online maps on the phone and see current location denoted by a flashing dot. However, 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 "Mobile Data Service" (MDS). This allows for custom application development using data streams on BlackBerry devices based on the Sun Microsystems Java ME platform.
In addition, BES provides security, in the form of Triple DES or, more recently, AES encryption 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. Beginning with OS 3.8 or 4.0, BlackBerry handhelds can access the Internet (i.e. TCP/IP access) without an MDS - previously 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.
Newer BlackBerry devices use the proprietary Blackberry Messenger software for sending and receiving text messages via Blackberry PIN.
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.
Future features
The current 8X00 series offers 2.5G/EDGE. The current "Bold" 9000 series offers 3G/UMTS and GPS.
The BlackBerry 9500/9530, aka BlackBerry Storm, offers a touch screen.
On September 11, 2008 Tivo and Research in Motion announced that soon TiVo users would be able to control their system from a BlackBerry phone. The integration was expected by the end of 2008. No price -- if any -- was disclosed.
Name origin
RIM settled on the name "BlackBerry" only after weeks of work by Lexicon Branding Inc., the Sausalito, California-based firm that named Intel Corp.’s Pentium microprocessor and Apple’s PowerBook. One of the naming experts at Lexicon thought the miniature buttons on RIM’s product looked "like the tiny seeds in a strawberry," Lexicon founder David Placek says. "A linguist at the firm thought straw was too slow sounding. Someone else suggested blackberry. RIM went for it." Previously the device was called LeapFrog, alluding to the technology leaping over the current competition, and its placeholder name during brainstorm was the PocketLink.
Nicknames
The ability to read e-mail that is received in real-time, anywhere, has made the BlackBerry devices infamously addictive, earning them the nickname "CrackBerry," a reference to the street-drug form of cocaine known as crack. Use of the term CrackBerry became so widespread that in November 2006 Webster's New World College Dictionary named "crackberry" the "New Word of the Year".
Many users also refer to BlackBerry smart phones in general simply as "berries", spawning a litany of offshoots. For example, "berry thumb" or "berry blister" is the soreness that occurs from handling the cramped keyboard.

The BlackBerry Store
In December 2007, it was reported that the first ever BlackBerry store was opened. While it is the only BlackBerry store currently in existence, it actually is not the first. There were three prior attempts at opening BlackBerry stores in Toronto, London, and Charlotte, but they eventually folded. The current location is in Farmington Hills, Michigan. The store offers BlackBerry device models from AT&T, T-Mobile, Verizon, and Sprint, the major U.S. carriers which offer the Smartphones. Employees are trained not only on the BlackBerry devices themselves, but on the regulations of each service provider.
RIM patent infringement litigation
In 2000, NTP sent notice of their wireless email patents to a number of companies and offered to license the patents to them. NTP brought a patent infringement lawsuit against one of the companies, Research in Motion, in the United States District Court for the Eastern District of Virginia. This court is well known for its strict adherence to timetables and deadlines, sometimes referred to as the "rocket docket," and is particularly efficient at trying patent cases.
The jury eventually found that the NTP patents were valid, that RIM had infringed them, that the infringement had been "willful", and that the infringement had cost NTP $33 million dollars in damages (the greater of a reasonable royalty or lost profits). The judge, James R. Spencer increased the damages to $53 million as a punitive measure because the infringement had been willful. He also instructed RIM to pay NTP's legal fees of $4.5 million and issued an injunction ordering RIM to cease and desist infringing the patents. This would have shut down the BlackBerry systems in the US.
RIM appealed all of the findings of the court. The injunction and other remedies were stayed pending the outcome of the appeals.
In March 2005 during the appeals process, RIM and NTP tried to negotiate a settlement of their dispute. One of the terms of the settlement was to be for $450 million. But negotiations broke down due to other issues. On June 10, 2005 the matter returned to the courts.
In early November, 2005 the US Department of Justice filed a brief requesting that RIM's service be allowed to continue because of the large number of BlackBerry users in the US Federal Government.
In January 2006, the US Supreme Court refused to hear RIM's appeal of the holding of liability for patent infringement, and the matter was returned to a lower court. The previously granted injunction preventing all RIM sales in the US and use of the BlackBerry device might have been enforced by the presiding district court judge had the two parties not been able to reach a settlement.
On February 9, 2006, the US Department of Defense (DOD) filed a brief stating that an injunction shutting down the BlackBerry service while excluding government users was unworkable. The DOD also stated that the BlackBerry was crucial for national security given the large number of government users.
On February 9, 2006, RIM announced that it had developed software workarounds that would not infringe the NTP patents, and would implement those if the injunction was enforced.
On March 3, 2006, after a stern warning from Judge Spencer, RIM and NTP announced that they had settled their dispute. Under the terms of the settlement, RIM has agreed to pay NTP $612.5 million (USD) in a “full and final settlement of all claims.” In a statement, RIM said that “all terms of the agreement have been finalized and the litigation against RIM has been dismissed by a court order this afternoon. The agreement eliminates the need for any further court proceedings or decisions relating to damages or injunctive relief.” The settlement is believed low by some analysts, because of the absence of any future royalties on the technology in question.
