The BlackBerry OS 4.5 Updates are coming to a close as one of the last carriers to release the update, Canadian carrier Telus, launched the 4.5 OS for their BlackBerry 8130 Pearl and 8330 Curve.  Unfortunately Telus BlackBerry 8830 users have been left out in the cold on this update which upgrades the application build to 4.5.0.077, but as a consolation prize this application build is still well behind version 4.5.0.89 which is currently available on Alltel Wireless.  If you decide to take the leap to OS 4.5 you will need to make sure you backup your device and have the BlackBerry Desktop software installed along with your USB cable and then you can hit the upgrade link here.
