Ok thanks for the delucidation..For number 4 it is unofficial because PAC devs never have made the official rom for our device. So it is built by the OP from the source of PAC rom itself. You can check the PAC website and you won't find sensation in their devices.
But thanks to webstar here we can enjoy PAC the AIO Rom
So, it is stable, but for the battery, what's your opinion on that?
Actually i'm on ViperS JB 3.1.2 (signature)
