02This rumor might not be for those of us on North American carriers, but it's surely a good sign for all of us if it pans out to be true... a reliable tipster from the UK has pointed me to O2's BlackBerry OS Download Page. Take a look at the notes: For the Curves and 8800s it says "Future Software Expected April 08", while for the 8100 and 8700s it says April/May 08. It definitely seems like 02 is working to make OS 4.5 available to their BlackBerry smartphones sooner rather than later. If you're new to the BB world and don't know what OS 4.5 is all about, click here to see what all of us CrackBerry Addicts are drooling over.

The really encouraging news is that our tipster also said he has been told by an "inside source" that the release date being aimed for is April 9th, which is just a few short weeks away. Here's to hoping!

Update: Check out the Comments Below as well as SLVR6's recent forum post . Seems it's more likely the handheld OS updates (ie. 4.3) will be released first (this is likely what's coming to O2 on April 9th), with the 4.5 rollout coming later. As is always the case with this kind of info, we'll just have to wait and see!
