Are there any news or even rumors on when will BlackBerry have their next os update? If yes, what are the possible changes/improvements?

I heard some time this month... we shall see.

It shouldn't be anything more than security fixes and updates under the hood with no visible changes on the exterior.

Keep checking the CrackBerry site for news.
