iPhone 3GS 16GB there are black flickering vertical lines on a white screen from the moment it turns on, it does not go to the apple logo at all. i've gotten it to connect to itunes to get this message every time...i am not forcing it into recovery mode, it just always is notice that itunes displays no info for this iPhone no serial number/capacity/or software version when i click restore i get this my first guess is that its a broken LCD but.... even though iTunes recognizes it as an iPhone, it cannot recognize it's serial/software. i really hope it's not the logic board. anyone have any ideas???
