Know Blackberry

BlackBerry is a line of wireless mobile device  that was introduced in 1998 as a two-way pager. In 2002, the more commonly known smartphone BlackBerry was released, which supports push email,mobile mesagging text messaging, internet faxing,web browsing and other wireless information services.Developed by the Canadian company Research In Motion (RIM), it delivers information over the wireless data networks of mobile phone service companies.

While including Personal digital asistan (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 .

Modern GSM-based BlackBerry handhelds incorporate an ARM 7 or 9 processor, while older BlackBerry 950 and 957 handhelds used Intel 80836 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) and include up to 256MB flash memory.

CPU

Early BlackBerry devices used Intel 80386 based processors. The latest BlackBerry 9000 series is equipped with Intel XScale 624 MHz 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 312 MHz ARM X scale 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 ARM X Scale ARMv5TE PXA900 chipset not supporting 3G networks. The 80 MHz 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.

Blackberry Internet Service

The primary alternate to using BlackBerry Enterprise Server is to use the Blackberry Internet Service It was developed primarily for the average consumer, rather than the business consumer. This service allows POP3 and IMAP email integration for the personal user. It allows up to 10 email accounts to be accessed, including many popular email accounts such as Gmail, Hotmail, Yahoo and AOL.
