Nokia 6255i / 6256i
6256i available at Radio Shack
With qualifying 2-year agreement. $259.99 without.
I've used the OBEX functionality to transfer some files from my BT laptop to the phone.
I've yet to get an MP3 to work as a ringtone, but that may be because it's too big.
It's not a bad phone, but I think I'll be returning mine.
The call quality is very good, as is the sensitivity (It gets good signals in areas where my LG4400 did not). There are some little things that bother me, so it's on to something else.
