I'm getting shut of my X10 in favour of an SGS, i'm loving android and the market (after using iTunes for the last 18 months) but the X10 i've had for the last three months has a couple of issues that get my goat. So i'd just like to make sure before buying the SGS, 1. Does the phone lock itself after making or receiving calls? 2. Is it loud enough to hear in your pocket if it rings? 3. Does it have Multi Touch? (SE told fibs about their X10 having it) I'm also led to believe its running on 2.1v, is that correct? I know i can research all this through Google before anyone pipes up, but i find it better to ask those who use it on a regular basis rather than someone who reviews it for a day.
