Hello evolver and welcome to the forums.
There are plenty of 4.5 OS versions out there, your carrier may not have approved one yet. Here's a link to what you might be looking for: http://crackberry.com/crackberry-4-5-os-roundup
WARNING: Upgrade your OS at your own risk. If you have not done this before, I would recommend reviewing this step by step tutorial: http://crackberry.com/blackberry-101-how-install-o

I was using the link here, which says 4.5 is compatible with the 8100; but the updater there says there's no actual update. Since this is my backup device, I don't desperately need the update; I just wanted to be current and thought it was really live. I can wait.
