how to find a blackberry serial number?

Answer 1

Though things looked a bit shaky for a while, BlackBerry manufacturer Research in Motion finally settled its longstanding dispute with NTP and shipped new versions of its Enterprise Server software recently and, more importantly, software development kits (SDKs). And if we learned anything from the company's legal mess, it was how much people rely on these devices to stay in touch.
Ease of use
The darling of corporate America (and many areas of government) wouldn't be so adored universally if it were complicated. Although an interface driven entirely by a thumb wheel might seem awkward and slow, users invariably find it easy to learn and quick to operate. Admittedly, the lack of a stylus and a touch screen--staples of other PDAs--slows down certain operations (such as hitting a link in a Web page), but the beloved built-in keyboard accelerates others, such as composing e-mail. Ultimately, the BlackBerry interface may not be the most efficient, but it's certainly one of the easiest to use.

Core applications
The BlackBerry OS does a better job managing your contacts than managing your calendar. The Address Book applet offers all the amenities you'd expect, plus contact grouping and unsurpassed integration with the phone and messaging apps. To send someone an e-mail message, for instance, you simply highlight the person's name, press the click wheel, and then select E-mail Joe Smith. There's no need to open the contact's record and navigate extra menus.
