Now, you're telling me you need a third party app to disable data usage on the phone? Perhaps there's a built in function for that? If not... uh...
Not I. I have no idea on a 'Droid. Wheelz says his phone has a "cellular data" toggle, and he's set it to "off". Therefore, he should not be seeing any data usage from Bell. Yet he's got the bill that says otherwise. A bit troubling, IMHO.
I use an iPhone4. It has a "Cellular Data" On/Off toggle built-in. I know for a fact that when it's set to "Off", it will not use any billable cellular data.
