Emails: After you buy a Blackberry, you'll need to sign up with any one of the wireless carriers like Hutch or Airtel. Once done, you'll be assigned an email address such as username@airtel.blackberry.net, which will deliver messages to your device. Although you could start using that address, you'll probably want to integrate your Blackberry with your existing email accounts. Just set up the forwarding rule in your Outlook and remember, you don't need to click 'Check Now' or 'Send and Receive' button -- new messages are pushed to your device as they are received.
Blackberry Web Browser: The Blackberry ships with an excellent browser capable of viewing a variety of formats including HTML, XHTML, WML, and SVG, and common image types as well. Not only can you access internet sites, but corporate customers can also use a server-side component called the Blackberry Enterprise Server to provide secure access to intranet sites. Another piece of good news is that most Blackberry handsets also support Javascript(a Language/script used to create web pages/web sites). If your mobile handset doesn't support Javascript, then the web site might not be displayed properly on the screen.
Security: Security-conscious companies will find much to like with the Blackberry Enterprise Server. All communication between the BES and handheld sets occurs through a single Transmission Control Protocol port, so firewall configuration is easy.
Also, all data that flows to handsets homed on a BES is encrypted. IT policies can be configured on the BES to centrally control almost every feature on the handset. For example, you can enforce a device inactivity time-out in which the user must enter a password to use the device, or you can specify a certain home page for the Blackberry browser.
Third Party Applications: The Blackberry is a fully J2ME-compliant device (one of the editions of the Java technology). This offers developers application programming interfaces, tools and supplies for creating networked products and applications for the consumer and embedded markets.
RIM encourages application developers by giving away a free, fully integrated development environment (tools used to develop applications for any technology), along with device simulators for every model. A large and rapidly growing community of third-party developers is creating applications for the Blackberry to keep you busy exploring new possibilities with your handheld device.
