They probably have a legal way out of this. No luck there.
I just burned my first one this morning and i will not stick a high-capacity SD card in the external slot anymore until someone finds a solution to the problem.
I think in Bugzilla Nokia is looking in the wrong places. Mine was burned while walking in the street. Nothing about transferring files, no connectivity whatsoever. And since it only seems to happen in the external slot i get the feeling that our devices are faulty.
How about that, Nokia? What about replacing the faulty N800's for ones that don't corrupt SD cards in the external slot? Ones that do have the physical connector/slot properly done.

Ton.
