just got this phone. i can definitely see where others are coming from when they mention a "tin cup" sound. one can definitely notice the difference between the sound on this phone versus other cell phones. that being said, the thinner sound doesn't really bother me much. the phone still delivers good sound quality- it is just that the sound is very metal like. otherwise, this phone is really cool in all other aspects. thin, light, loaded with features. wish it had voice dialing.
