anyone knows how to fix the microphone on this thing?

[cantfind]

When talking on the phone, about every second word sounds quiet (almost silent) on the other end of the call.
When talking in speaker mode its ok... I've tried updating to the latest ROM, it didn't help.
My guess is that the mic's connections aren't connected well enough... Anyone knows how to open the phone up (or has any other idea)?

mm something similar happens to me. I'll try the last rom and let you know if it does the magic.
