I'm thinking about picking htis up in a week or so but have not been able to find many reviews about it. If you have this phone, would you be willing to answer the following?

a. How different is its operating system from other Nokia phones?
b. Is the external display customizeable (to display something other than the analog clock)?
c. There doesn't appear to be any external controls for the mp3 player. Are they on the sides of the phone? Are they easy to implement but not so easy as that if the phone was in a pant pocket they'd be accidentally activated?
d. Have you tested it 1) in an underground parking garage, 2) in the country? If so to either one, how does it's reception fare? (and in general)
e. How customizeable is its
f. How does the music sound? Does it really require a special attachment or can you just hear it through speakers or headphones? Is there an equalizer?
g. Same questions for the FM radio as for the mp3 player (f).
h. How's the speakerphone fare in a car environment?
i. General impressions?
