I have owned my Canadian version of the Galaxy Tab 7.0 plus (wifi only) for about two years. In Canada, we are still on Honeycomb. I had called Samsung Canada about three times in the last year regarding the official update. They told me that there was no new information and all I could do was just wait for a notification for any new update.
I finally just got tired of waiting. I did not want to root. I searched and found the following links:
