To anyone who has a NC10...I have a C905 mobile on Orange with "free" data after 7pm-7am. I called them up today, and was talked through instructions on setting up my phone and NC10 for connecting to the internet using the phone. Job done in 10 minutes! Forum info was a bit blah, and the guy who helped me sorted me out in no time. Now free to access the internet everywhere after 7PM using the phone :)
Might be useful if you have got a quite recent mobile, and want to use your NC10 away from your wi-fi connection.
