If you love to use a BlackBerry, the credit goes to the BlackBerry operating system (BlackBerry OS) that facilitates the user friendly features of the BlackBerry platform developed by Research in Motion. The BlackBerry operating system supports multitasking and supports enables input devices such as the trackwheel, trackball, trackpad and touchscreen. Behind the scenes, the BlackBerry OS excels in its built-in support for corporate email that allows complete wireless activation and synchronization of email, calendar, tasks, and notes with Microsoft Exchange, Lotus Domino, or Novell GroupWise when combined with BlackBerry Enterprise Server. Apps4Rent offers reasonably priced plans for hosted Exchange and BlackBerry Enterprise Server hosting.

For an operating system that originally started out as a two-way pager in 1999, BlackBerry OS has come a long way. As early as 2002, BlackBerry Operating System provided multitasking and supported everything from Internet faxing and text messaging to push email and Web browsing. The current BlackBerry operating system (BlackBerry OS 5.0) does the same, but supports input devices as well, such as the trackwheel, trackball, and touchscreen. It also supports WAP (Wireless Application Protocol) 1.2 and MIDP (Mobile Information Device Profile) 1.0 and a subset of MIDP 2.0. Research in Motion also offers BlackBerry e-mail client on numerous non-BlackBerry devices, such as the Palm Treo, through the BlackBerry Connect software.

The BlackBerry operating system, BlackBerry Enterprise server and Exchange bring unparalleled convenience, reliability and security to mobile computing. Easily interact with other corporate information while on the go, such as calendar, tasks, notes and contacts. The OS also works with other email client software besides Outlook, such as Apple Entourage and Lotus Domino. The Blackberry OS also supports the ability to download, view, edit save and attach critical documents in Word, Excel, PowerPoint or PDF format.
