We weren't expecting to hear too much about it, but RIM's year-end / Q4 fiscal 2011 earnings call uncovered a good bit of information surrounding BlackBerry OS 6.1. As you've likely learned by now, we weren't exactly throwing our iPhones and Droids into the nearest refuse bin after handling the Torch, and it seems as if quite a few bigwigs at RIM were equally disappointed. In response to a question about the rollout of BB OS 6.1, we were told that it would truly be a "major upgrade" over what's out there now, and rather than being an incremental update, it'll be more like "an overhaul." The company made no bones about its excitement for the release, and frankly, we're having a hard time keeping our expectations in check after listening in. Thankfully, we'll be able to get our paws on it at some point this spring, with a number of elements to be teased at BlackBerry World this May. Naturally, we'll be there to keep you up-to-date with how it's rolling along.
