Although most Blackberry's aren't optimized for web browsing like devices such as the Iphone and Google's Nexus One, they have seen the value in QR codes to exchange information in the mobile world.
Blackberry messenger 5.0 has included a QR code reader in the latest software update. Users can now share QR codes containing links, phone numbers and other contact information. Better yet, they can read Tappinn QR codes in magazines and retail stores using the phone's camera and the BB messenger app together.
Welcome to the future, Blackberry. Please ditch the keyboard and get bigger screens too!
