I have an A310 and I have heard that when you put the phone into silent mode, using the one touch feature (holding down the # key), that the phone vibrates when a call is recieved. My A310, when i put it into silent mode is only silent, no Vibrating whatsoever. Can anyone help me out with this? Do i need a software update? Is my phone a lemon? or does this phone not vibrate when in silent mode and people are mistaken. Any help or experiences with this feature ON THE A310 would be much appreciated. Thanks.
