Hello, I have a regular unhacked/locked phone and it's on 1.0.2. I never upgraded to 1.1.1 because of the rumor of the battery draining issue. I have very good battery usage. Now that 1.1.2 seem to have fix that, I'd like to upgrade. So I'd like to hear from anyone who upgraded from 1.0.2 to 1.1.2 whether there was issue or not. Thanks in advance.
