Then you probably don't have one of those fancy new things called smartphones, as they are all very locked down and don't allow you to access or modify a lot of system settings, limit access to files apps create, don't allow to move some apps to the SD card, some of them even disallow you from installing apps from anywhere but their own app store. Certainly you don't have one of those devices that treat the user in a completely patronizong way.

Of course, you can liberate yourself quite a bit from the draconian rule of the manufacturer by rooting the device, but then you're also able to disable cell broadcasts permanently...
