    Same problem here. Started on 5/31/08.

    Cingular is telling me it's a hardware problem but it seems very strange this should be happening to multiple users in the same week. If I use the speakerphone, I'm fine but if someone calls me or I call them --they can hear me but I hear nothing.



    Has anyone found a solution? I love my phone and I don't want to buy a new one just yet.

    I had my CU400 replaced under warranty about two months ago for the same problem. One day I was unable to hear ANYthing dialing out or receiving **UNLESS** I had it on speakerphone. Today, my new CU400 started doing the same thing. I am so angry. The warranty period is now over, I have one more year on this contract and can't afford a new phone. I do NOT recommend this P.O.S. to ANY one. I have never had any other cell phone with issues before and to have one model have the same issue twice with two phones in just several months tells me a lot.

    The ear piece speaker does not work, but the speaker-phone speaker does.
    Tried adjusting volume, removing and replacing battery, any and all possible setting adjustments - nothing has helped.

This problem has been driving me crazy too, but I found that if you connect to a blue tooth headset and when you are talking go to the "option" on the top right soft key and choose "use headset" you phone will start working again. It worked for me and I hope that it will work for you too.

    Amendment on what I have to do to correct this issue. It seems that this is a bluetooth issue. I don't recall having any problems until I started using the bluetooth feature. Anyway my phone went back to having the same problems with not being able to hear unless I had the caller on speaker. My first solution works, but only on incoming calls. That is so weird, but wanted to update everyone on the process.





    First Solution : This problem has been driving me crazy too, but I found that if you connect to a blue tooth headset and when you are talking (on an incoming phone call) go to the "option" on the top right soft key and choose "use headset" your phone will start working again. It worked for me and I hope that it will work for you too.

it seems to be an hardware fault.since as you said you cant hear the caller, your phones headpiece is seemed to be faulty. you need to replace it form a nearest service center.also before that just try pressing the up arrow key on you phone while calling it may increase the volume if you accidentally decreased the headpiece volume.
good luck
