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 assistant and portable media player. They 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. They support a large array of instant messaging features, including BlackBerry Messenger.
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 after OS 5 support up to 32 GB microSD cards.
