I have the same fade problem!!!

The fading happens while talking to someone and it depends on how hard I press my ear against my phone..... shaking my phone around a little bit while calling also solves the problem, but it works the other way around too: if im walking, it can fade out and i wont be able to hear that person anymore... :P

The speaker works, so it MUST be some hardware (loose cable??) problem. If I plug it into my carradio or headphones, it works too,btw.

Important: Since a day, when I shake my phone, I hear something loose around where the ear-speaker is. Something is definately wrong inside my phone

Anyway, this phone is useless like this, because I can't make proper phonecalls anymore. For the people that dont know what the fade problem is: Imagine talking to someone at max volume and then out of nothing 5 sec at lowest volume and then back to max volume.
How can I fix it myself? I'm 700km away from the nearest Nokia service point. (They don't even sell this phone in my country...)
