I have a Blackberry Bold 9000 and previously it was working properly but recently on the other hand, there is a small problem, always when I turn on the phone, the display will be fully oriented and I am not able to go on, switched off after a time, then the device itself. I can start the machine if I pull out the battery and then wait off, I am not able to install too, as I said it just turns off itself.
