BlackBerry's suffered some PR hits in recent weeks thanks to a service outage that left a nation of addicts without their push Email for a day or so.  But let's face it - nobody's giving up their BlackBerrys because nobody does mobile Email like BlackBerry does.  RIM's new breed of handsets add a little fun and style to the favored handset of the modern executive, and the T-Mobile Curve 8320 is arguably the most full-featured BlackBerry to date.  What T-Mobile lacks in the way of a 3G network it tries to make up for with a handset that adds WiFi, UMA calling, and myFaves support as compared to the mostly similar Curve 8300 for AT&T.  The result is nothing short of one of the best smartphones currently on the US market ? especially if you can't live without your email wherever you go.
