Connex And RIM To Offer BlackBerry In Romania

Bucharest, Romania and Waterloo, Canada - Connex and Research In Motion (RIM) (Nasdaq: RIMM; TSX: RIM) today announced plans to offer BlackBerry®, a leading wireless  platform, to mobile customers in Romania.  BlackBerry will operate on Connex’s GSM/GPRS network in Romania and international roaming will be supported in countries where Connex has GPRS roaming agreements in place.

BlackBerry provides always-on, push-based, mobile access to e-mail and other communications and information for both individual and corporate customers.   The BlackBerry 7290 Wireless Handheld™ will enable Connex’s subscribers to access e-mail, phone, text messaging, Internet browser, organizer and corporate data applications via a single, integrated device. The high-resolution color screen displays crisp images with support for more than 65,000 colors, offering superior battery life for optimal wireless performance. With BlackBerry, users can easily and remotely manage their e-mail, appointments and contacts and access corporate applications while on the go.

“BlackBerry is a proven solution and we are pleased to be working with RIM to include this powerful communications tool in our current solutions portfolio,” said Ken Campbell, Chief Marketing Officer at Connex.   “Romania has a rapidly growing enterprise sector and we are committed to introducing innovative products to enhance the business and personal communications of mobile professionals.  By using BlackBerry from Connex, subscribers will have easy access to communications and information while away from their desk.”

“The popularity of BlackBerry is growing rapidly around the world, and we are very pleased to work with Connex to introduce BlackBerry to its customers,” said Don Morrison, Chief Operating Officer at Research In Motion.  “Well over two million people are already enjoying the BlackBerry experience today and we expect Connex customers will also be very impressed with the power and freedom of wireless connectivity via BlackBerry.”

For corporate customers, 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 e-mail and other corporate data.
