The one big problem most people seem to have with the IP4 is the poor notification system. I wonder "if"
wanted to....could they use the led on the camera to use as a notification for a missed call/email/sms ? Through a software update this would be possible???? We could then just lay they phone screen down and take a peek for the "glowing" led flash...
Good/ bad idea?
I wonder if internally if it is even technically possible? 

Good/ bad idea?
