The local casino down here has a rule that cell phones void the BBJ, therefor they aren't necessarily allowed at the table. It's not really enforced, and most people get away with it as long as they aren't blatant. I've never seen a hand ruled dead from this rule, although usually if someone is on their cell phone the dealer will usually politely ask if they would like to be dealt out.

I receive a phone call from a family member about a family emergency, and then get dealt in a hand. I tell the person on the other line that I'll call back after this hand, and I can't talk at the moment and quickly put my phone away. She waits for me to throw in my $5 limp, and then immediately says, "your hand is dead."
