Thanks for the explanation. Will data usage be turned on or off by default? "Silently" having data turned on by default and allowing the user to turn it off later in the application settings may not be good enough for some people. Probably the best thing to do is provide a first-run-only dialogue which will ask the user whether he wants data turned on or off, with a full explanation of the pros and cons. If the user chooses "Off" on the first-run dialogue, no data will have been sent. The reason I say this is because I want to try and protect you against a backlash like that which has happened with the PR1.2 compulsory My Nokia registration. For some people, being able to unsubscribe or to turn off data later isn't good enough - they want to have never subscribed or sent any data.
