I make a call in a somewhat noisy environment and the company on the other end of the phone gives a number of options by pressing 1-4 on the keypad. One major problem, its an Iphone 3g and the proximity sensor has blacked the phone. I cannot choose any of the options and the call becomes a waste of time. Is it possible to turn the sensor off as using the speaker wasn't appropriate at the time also?
hmmm for me all i have to do is move my head away and the screen comes back on, allowing me to hit which ever number i want.
