Cell broadcast support on Android?

Does anyone know if there is a suppo开发者_JAVA技巧rt for cell broadcast on Android? If yes, can anyone point me to any example that shows how to use it? (e.g. receive messages on some channel)

Thank you.

There are quite a few sites that come up on google about this..

I think there are restrictions in certain countries - Brazil for instance will only allow you to use channel 50 (from what I read).
