Just for the hell of it, I activated my old 6000 until
I get the 6400. One thing I noticed right off was the
better sound quality of the 6000.

I took both phones, the 4900 and 6000 and dialed *2 and
listened to the music. The quality was very clear on the
6000 where the 4900 sounds like it wasn't vocoding very
well (is that a word - vocoding?), anyway most of ya'll
know what I'm talking about. With the 6000, I could hear
every musical note; but with the 4900, some notes were
dropped or mumbled.

Another thing I noticed was the 6000 can't render some
web sites, like AccuWeather, but then its not a true
Vision phone, so that might be part of the problem. I'm
going to test the 6400 first before I buy.
