Nokia 6101 / 6102

We recently switched to a Cingular family plan with two 6102 phones. I am not very impressed, mostly because we simply can't hear each other! Yes, on both phones I turned on the Automatic Volume Control and also turned up the volume all the way. We still have a hard time hearing each other.

So - I have three days to choose another phone from the Cingular store. What phone would you recommend? I'm disappointed because I expected to be much happier with the 6102. I like flip phones in general but are the Nokia candy bar-type phones any better with volume? Are there any Samsung phones offered through Cingular that you think are great?

Thanks for any input!
