Cable & Wireless Launches BlackBerry in Panama

Panama, Caribbean and Waterloo, Ontario - Cable & Wireless and Research In Motion (RIM) (Nasdaq: RIMM; TSX: RIM) today introduced the BlackBerry® wireless solution to Cable & Wireless customers in Panama. Cable & Wireless is offering the Blackberry 7290™, the BlackBerry 7100g™, BlackBerry Internet Service™ and Blackberry Enterprise Server™ v4.0.

The BlackBerry platform, together with the Cable & Wireless GSM/GPRS network, provides mobile professionals and organizations with always-on access to email, phone and data applications from a single device. BlackBerry users can manage their information and communications while on the go.

The BlackBerry 7290 and the BlackBerry 7100g deliver an exceptional voice and data experience with quad-band support (850/900/1800/1900 MHz) for domestic and international roaming* and feature Bluetooth® support for headsets and car kits. In addition, both devices feature 32 MB flash memory and 4 MB SRAM.

The BlackBerry 7290 incorporates a full QWERTY keyboard with highlighted number keys for easy dialing and typing. The BlackBerry 7100g features SureType™, an innovative keyboard technology that effectively converges a phone keypad and a QWERTY keyboard to fit elegantly within the size constraints of a traditional 'candy bar' phone design.

BlackBerry Enterprise Server software tightly integrates with Microsoft® Exchange, IBM Lotus® Domino™ and Novell GroupWise™ and works with existing enterprise systems to enable secure, push-based, wireless access to email and other corporate data. The BlackBerry Enterprise Server v4.0 offers exceptional manageability, enhanced security and simplified application development. 

For individuals and smaller businesses, BlackBerry Internet Service allows users to access up to ten supported corporate and personal email accounts (including Microsoft Exchange, IBM Lotus Domino and most popular ISP email accounts) from a single device.
