I have a BlackBerry with voice and the BBM plan (no internet). I recently switched models and am suddenly getting hit with data charges that I never received on my old model. It now allows browsing on the network, which the previous one never allowed. We don't use the browser so I am assuming that the device is sending out status updates and other stuff. How can I get all data shut off completely with the exception of BBM? If I turn off data on the network via the device, BBM won't work, so I can't use that as an option.
