UPDATE: The update 188.8.131.526 is now available!
Like a bolt of lightning, it emerges that the PlayBook should be receiving an update shortly.
Direct from the BlackBerry Dev Twitter account, we've been told that there will be improvements to account services, browser, & audio boost.
This may not be available on the 3G / 4G PlayBooks, as there is a disclaimer for carrier availability.
It's great that there's an update - but I think that all PlayBook owners really want to know Where's Our BlackBerry 10 Update?
Regardless, I'm looking forward to this update for now.
