Same thing here. After only two weeks, one morning, I removed the charger connector and the microUSB thingie just came out. I took the phone to the official Nokia Care here in North Finland but soon, I got the answer: "our warranty does not cover this, it is BER (Beyond Economical Repair)".

Yeah right. There is obviously something wrong with the connector: take a look at this (sorry if someone has already mentioned this page).

This could be a hilarious thing if it had happened to an inexpensive, say 20 €, equipment. But it's a 600 € phone. And the same thing has happened to a lot of people. So.. Well, you've probably gotten my point already .
