Hello Everyone, I recently ordered a Samsung Galaxy S2 T989 model from Tmobile which should arrive in about a 2 days. This is my first android phone so I'm pretty excited. It comes preloaded with Gingerbread 2.3.6 ver and I was wondering about ICS 4.0.4. How does it compared with GB 2.3.6 version? I read horrible things about 4.0.3 and how it lags and drains battery fast. I was wondering if they have fixed those issues addressed in the 4.0.3 version. What are the pros/cons of upgrading to ICS 4.0.4? Any answer will help me tons.
