On a 14 Hour Non Stop, I forgot to switch the BB off in my hand luggage (actually if you switch it off you apparently have to wit till it turns off before returning to holster otherwise it does not turn off).
Needless to say I had roaming charges (BB mails kept flowing so got charge a daily charge for every country it logged into) from Iceland to Afghanistan on my Phone. Don't think I will ever forget that.
As far as talking on the phone. I prefer switching it off as soon as i am about to board and on again after I have my luggage. The few hours of peace in between from the talking and ringing is delightful.
