The BlackBerry Z10 and the BlackBerry Q10 may be the new kids on the block but the BlackBerry PlayBook is far from forgotten by the company. BlackBerry is pushing an update out for their only tablet which is 132MB in size and updates the software on the device to the 2.1.0.1526 software version.
This unfortunately isn't the BlackBerry 10 update that many will be expecting for their PlayBooks but is a good indicator that the update may not be to far off.
The update rebrands the BlackBerry App World to BlackBerry World, allows SMS chat through BlackBerry Bridge , adds improvement to the browser and boost the volume of the tablet. The update also adds support for in-app payments, to benefit developers.
