i read a thread about how verizon can cut your connection if they feel you are abusing or slowing down the network by your data usage and then charge you overage fees.
I don't use it all the time but there have been some days where I listen to it for several hours. I think just this Monday was when I listened to it at work all day, then walked out to my truck, plugged it in to my aux input, and listened to it all the way home. Haha I love pandora.
