The 8700c is far better than the 7290 in all respects (except toughness) including the volume of calls using the ear piece. The 7290 for me worked well with the wired headset as does the 8700. So yes, you'll see a big improvement.
No dust problems for me at this point, using the phone since December. Personally I wouldn't care if I received a refurb as long as the screen wasn't scratched. It's a phone and probably will be replaced in a year.
