I had the opportunity to get it today but there are no cases for it yet so I didn't.
This is an awesome phone, there is a really good balistic case for this phone.
Hi, i have this phone too, and a really good case is the Trident Aegis Case. You can find it here:
Samsung Galaxy S II (T-Mobile) - Tridenteer.com
There really good and aren't really that expensive. (y)
