**Update: CrackBerry has confirmed that these boxes do indeed contain the security display devices for BlackBerry PlayBook 4G LTE devices. Look for the launch sometime this week or next.
We had originally heard that the BlackBerry PlayBook 4G was slated for a Q4 2012 Launch and then we heard last week that date had been pushed up to July 31, 2012. Well, yesterday was July 31st and the day came and went without any PlayBook 4G launches. However, that doesn’t mean that the 4G PlayBook isn’t coming very soon. Select Rogers stores across Canada have been receiving display security packages marked “PlayBook Security.” This indicates that the stores should be getting the 4G PlayBook in sometime soon and we should see a launch in the coming weeks. We’ll let you know as soon as we hear more.
