UPDATE: Some users are reporting that OS 4.2 is still showing as the latest OS for their device…
Though it was hinted that this was coming yesterday on the forums I was surprised to see that it actually went live today. Just head on over to www.blackberry.com/upgrades from Internet Explorer and click the UPGRADE NOW button. It will then proceed to download a ~25mb ActiveX control which is a watered down version of desktop manager.
NOTE: I cannot be 100% certain that OS 4.5 is available for all devices or what the limitations are but the installer clearly hints that OS 4.5 is part of the process. If it is not available now it will be very soon. I just can’t verify since all of my devices already have 4.5.
It will then search to see if you have the latest OS. I already have OS 4.5 so it did not find any upgrades for me. Let me know what OS it gives you back.
At the end of the process you can enter in your email address to be notified if there are any further OS upgrades. What I don’t understand is why they could not integrate this functionality with Desktop Manager….
