phone's fault!

My cell-phone, w910i is Faulty!
When answering calls, the other party can't hear what I'm speaking
even thou I might be shouting on the phone.
So, pardon me if you guys don't hear anything during the phonecalls.
But, it's alrights. I will be using another spare phone!

Check out this cyber-shot phone, c905!
Freaking cool @!#$#%, 8.1 mega pixels / xenon flash!
