Turning off cell broadcast messages in Ice Cream Sandwich

The phone is a stock HTC One X. The settings menu does not include a checkbox to enable/disable CB messages. They just keep popping up. **Update**: Halfer already gave the link to the wikipedia article about CB, which should explain it in more detail than I ever can. What it means to me is that I get location information as I move around in town. The screenshot here shows the checkbox for this feature on what I believe is Gingerbread: **Update 2**: And this is the extremely boring message. This particular one just shows the carrier name, so it's even more useless and annoying than if it were showing location information: [](http://img51.imageshack.us/img51/5582/201206111740201.jpg)
