Greetings from Greece everyone!

I have a Sony Ericsson W810, and I am very satisfied with it. Only problem is: TRANSMITTER BUZZ!!!! The provider I have broadcasts at 1800MHz, and everytime I am on a call, I hear a faint "buzzing" from the earpiece just like the sound a speaker does when your phone is about to receive a message or ring. This noise is reduced (but it's still there) when I am on a wide area where it's easier for the phone to send/receive signal (a mainstreet in Athens, or even outside my house), and it is getting louder and more audible when I am on a silent room or a basement for example. Now, I have made a research on the internet and I am still very comfused. Some people say that this "buzzing" is a problem with the phone's hardware, while others say that this is just how this phone works and there is nothing you can do about it.... I have send it to sony ericsson's service here in Athens, they tested it for a week (!!!!), or at least that's what they told me.... and they found no problem with the phone. Although I use my handsfree to speak (and there is no interference or buzzing there), I am still pissed off with this problem cause sometimes I am forced to hear this buzzing when I don't use the handsfree and the phone is stuck to my ear!!! I am about to sell the phone just because of this problem and I really don't want to..... As far as I know lots of other users have the same issue with it. And also lots of motorola and nokia users hear this buzz .
All I need to know is: Is this buzz a known issue with the w810 (I have spoken with other W810's and some have the same exact problem, and others dont...)??? Does it depend on the the frequency your provider broadcasts???? Can it be fixed (I have upgraded to the latest firmware but nothing happens)???? Does this buzz means that the phone emitts more radiation than the ordinary values (something that can be hazardous to your health)???? Do I just have to get used to this buzz????? I don't want to get rid of this phone.... It's excelent otherwise.......

Thank you in advance for your answers!

P.S. When I use a GSM 900MHz card, things are way better and the buzzing is reduced a lot.......
