  This is something I don't understand.  A friend of mine gets his
mobile phone through work.  It's some kind of BlackBerry.  His
employer switched from AT&T to T-Mobile.  They're both GSM carriers,
so I expected them to be about the same.  Yet he says he gets
significantly worse coverage with T-Mobile than with AT&T.  Anyone
know why that might be?  Something to do with roaming, perhaps?
