Last month we told you about the new BlackBerry Messenger coming with OS 5.0. Yesterday links to the BlackBerry Messenger client leaked on the Internet for all recent BlackBerry devices, but people kept asking for OTA links. So our dude, 0mie over at 0mieTechSupport, made the downloads over the air and hooked it up! We decided to host them here as well, so feel free to visit our links from your BlackBerry Browser and it should prompt you to download it.
Please remember that this BlackBerry Messenger version is in beta and may still be buggy. We STRONGLY encourage you to backup your BlackBerry before upgrading. We can not be liable for any damages it may cause.
EDIT: DO NOT UPDATE IF YOU HAVE ANY OS LOWER THAN 22.214.171.124!
EDIT2: If you have any problems with this you must leave a comment with what BlackBerry you are using, and the OS you are running.
EDIT3: RIM seems to have enabled the Avatar feature today. If you still have trouble getting your Avatar seen, please attempt to re-upload your Avatar and/or restart your device.
EDIT4: Please follow this link if you wish to downgrade back to your original BBM. http://forums.crackberry.com/f86/how-can-i-downgrade-old-bbm-271634/
FINAL EDIT: The official BlackBerry Messenger 5.0 has been released by RIM. We recommend that you download this version instead of the beta versions. You can read about the official BBM here: http://smartphonenation.com/2009/10/blackberry-messenger-5-0-officially-available-in-app-world/
