This stylish -- uniquely so -- cell phone from Nokia is large but surprisingly light, and the color screen is one of the best I've seen on a cell phone.  The circular dialing pad does take some time to get used to, but likely not as hard as you'd think.  The ring tones are nice and loud enough for everybody, and the built-in camera is easy to use.  But T-Mobile ranks as the worst mobile operator in the country.  The German-owned company has sporadic cellular coverage outside the New York metro area, tends to overbill its customers, and has a user-unfriendly website.  While I wholeheartedly recommend the 3650, I advise you stay away from T-Mobile.  Get AT&T Wireless instead.
