I've read posts on XDA that ICS for Canada started rolling out a couple of days ago,
so hang in there.
But if you really don't want to wait, by all means flash the US or the UK version (the first time I did it I used UK and it worked fine on my US wifi only version).
Since the update started a few weeks ago, I've flashed the UK version, back to HC 3.2, and
back to ICS several times. I've flashed with Odin, updated with Kies, and updated
via OTA. All three methods worked fine.
I've also flashed CWM, and rooted.
The reason I'm posting this is because I was a total noob at it when I did it the first time.
It really is very easy. Just follow the instructions carefully, and you'll be good to go.
There are numerous guides to do these things. If you're interested in rooting, just make sure
you have the correct CWM and root (SuperUser) files for your device.
I've rooted my tab several times now, and it's working great.
If anyone wants to root their tab, I have the correct files, and I'll be glad to put them in my Drop Box.
Sorry for the long post; just want share my experiences with this terrific device which is now even better than t was, and I thought it was great with HC 3.2!
