For the second time over the course of a year, it would seem as though Sprint’s ready to kill the BlackBerry PlayBook. A new version of the PlayBook OS is set to debut in February, but according to an EOL (End of Life) report out of SprintFeed, Sprint isn’t prepared for the wait. Not even for a week. Of course, the WiFi-only PlayBook will still be available at various office stores like Best Buy and from RIM directly, but Sprint’s execution of the PlayBook marks the end of the product’s life on a carrier shelf.
