random question, moreso for the s/x owners i guess (since the 3 will probably be similar) - how long is the buffer on the streaming radio? i live in an area where cell reception is spotty in the general vicinity of my house (in a canyon, once i get about a mile or two away i've got full signal but right around the house it's very hit or miss). how much does it buffer? am i going to be SOL around my house, or will it buffer enough to get me through the dead zones? for example, will it buffer enough in my garage on wifi to get me to the mile or two down the road where cell service picks back up?
