As the title suggests I have a 8900 and I am womdering if o2 is ever going to upgrade to OS 5?

OS 5 is available officially.
Yes, from another carrier, but that doesnt matter.

That's yet another cool thing about BlackBerrys - they're largely carrier agnostic. Any carrier's OS release will work with any other carrier. Grab the latest OS from sticky thread at the top of the 8900 forum and let 'er rip.
