Blackberry (part 2)

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 email and calendar, as well as with Lotus Domino email. OS 5.0 provides a subset of MIDP 2.0, and allows complete wireless activation and synchronization with Exchange email, calendar, tasks, notes and contacts, and adds support for Novell GroupWise and Lotus Notes. The BlackBerry Curve 9360, BlackBerry Torch 9810, Bold 9900/9930, Curve 9310/9320 and Torch 9850/9860 feature the most recent BlackBerry OS 7 (as of July 2012).
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.

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.
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.
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. 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.

CPU

The latest BlackBerry devices such as the Bold 9900/9930, Torch 9810, 9850/9860 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 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. 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.
