Sadly, this seems to be the state of the electronics industry in general. I just finished reading about a Lenovo service call where the on-site technician destroyed a motherboard before the owner's eyes and the machine had to be sent to a repair station - and when it came back it was completely scuffed and damaged on the outside after being sent in with like-new condition. This is still unresolved after weeks and weeks, even though the owner has the expensive extended on-site support & repair service.

You're lucky with your E90 - you didn't pay another $300 for extended warranty and then end up with some dumbass technician destroying your device in front of your very eyes.

That said... it's very sad that such an elementary part of the phone (microphone) should fail on a phone built buy a company that's been making phones since... well, pretty much the dawn of phones - on an $800 phone, no less.

And why are the repair centers not authorized to repair phones? What's the point of having a repair center then?
