Nokia 6682 / 6681

I love nokias, I always had them they are user friendly, I need email access and bluetooth. and i cant seem to get used to my treo 650, i want a good bluetooth phone with email recieving capability, is this the phone for me, ive read many of the reviews and they are generally positive, but i still nbeed to ask;

1) is the email recieving as good and readable as the treo?
2) are there any updatres to the glitches that some of the happy users mentioned.

3) I have cingular, so which one is best for me 6681 or 6682 or what?

Thanks friends!
