I have a GT-P6200 here in the Philippines.
It is not "locked" to any carrier.
I tried to update it to ICS, 4 times thru kies but was unsuccessful.
It kept on "timed out" for some reason.
The farthest I got was 42%, 37%, 21%, 5%.
I will try again tonight. Hopefully this time it will work (crossing my fingers)
By the way, when I open kies in the office and plug in my tab. The upgrade wont be available.
But when I am at home, I could get the notification for the upgrade.
And I just live about 11km from the office. (wierd or I have messed up :-))
I feel like having a new P6200 in my hands.
The only setback I have noticed so far is my map apps.
It could not locate my current location by using GPS only!
I need mobile data for it.
Unlike when I was in Honeycomb, GPS works great even without the aid of a mobile data.
