It isn't all about the Z10, you know. BlackBerry just gave PlayBook owners some equal time in the sun with a new (if unceremoniously titled) 188.8.131.526 update. The release puts the tablet through the same BlackBerry World rebranding we've seen on the Z10 along with truly functional improvements, such as support for in-app payments and the addition of SMS chats through BlackBerry Bridge. Less conspicuous audio and browser upgrades lurk underneath. While it's not the BlackBerry 10 upgrade that some would crave, the patch is proof the company still has love for its original QNX-based gadget.
