Both microphone and loudspeaker positions have been designed for that puprose, loudspeaker on the front right and mic in the front left corner (of the keyboard). One reason one holds the communicator "the wrong way" when talking, the bottom towards the ear, the phone keyboard away from the head. Headsets are also getting more and more standard, especially among those who use commuting time to keep in contact. It is not by accident that FCC measures SAR when in a holster. Managing the timeslots is simple, GPRS-data is "best effort", voice is highest priority (when someone actually talks, DTX, on the average half of the time). Half rate coders are also used, some implementations have been found to be pretty buggy, do not recover from certain error situations. HSCSD gives a guaranteed circuit switched Nx10kbps data channel for those who need and pay for it. Ilmarinen Obviously, without SIM cards it would be easier, no need to test for roaming functionality and fear freely roaming handsets in foreign networks, just as safe as playing alone in ones backyard. Btw, if you were to ask out a girl on a movie, restaurant,etc, over the phone, would it feel kind of natural to browse through something together in hope of more browsing later on?? Ever done any chatting or SMS messaging while on the phone with somebody else?? Sorting out where you all will meet,etc (or are meetings just a question for the secretary??) Or walked through a parts list, block diagram, some assembly code, XLS document, etc,etc with someone over the phone, out in the blossoming field??
