Rumour has it that many Nokia handsets were dispatched with beta debug software on it that in the background sent text after text to Nokia to report and faults with the original 300 prototypes that went out at the Maemo Summit. I think that this was accidently left into a few batches being shipped round the world which would have ment users without knowing it sending multiple sms messages on an international number. I can only assume they are taking the stock back to the countries such as sweden etc and making sure they are flashed with correct firmware.
