I have had my N900 overclocked for a long time. I didnt take the phone to service, I shipped it. I still have the warranty I got on it, so the phone is repairable, since Nokia has announced that as long as the phone is still under warranty, the micro usb issue will be repaired. (so i guess no, overclocking it doesnt prevent repairing hardware that HAS NOTHING TO DO with overclocking) which was my original question.
deceit, trickery, sharp practice, or breach of confidence, perpetrated for profit or to gain some unfair or dishonest advantage
