An update is coming out of the blue for the Z10, Big Blue that is. The small update promises to bring enhancements to battery life and other general improvements.
However there is also a bit about providing support for third party applications. This may mean that BlackBerry is getting ready to launch Skype on Blackberry World and possibly integrating it whith BlackBerry Hub. We won't have any way of telling until Skype finally releases some time soon.
In the mean time enjoy the battery life improvements, and let us know if you find anything exciting.
