It seems that iPhone OS 4.0 beta 4 has a hidden feature/bug, which until now went unnoticed, but an iPhone user accidentally discovered it while playing with his phone, so if you press the Lock button 3 times in a row, in iPhone OS 4.0, the screen will become completely white and we can use the phone as a mini flashlight.
There are enough applications in the AppStore or even in Cydia that can reproduce this functionality, but it would be interesting if Apple would introduce it as a feature of iPhone OS 4.0, however I tend to think that it is a bug and not an option in itself .
Would you like this functionality to be introduced in iPhone OS 4.0? Would you be able to help with anything?
