assuming you have version 1.1 some of the things are a little tough to figure out. first i'll go over siri, once your at siri type in list to see available searches, once you found a search you like go back to the siri home and type in the thing you saw in list :D Post questions in comments ;)

What is the key?

S5NE3Q4, also if the siri questions don't work maybe try taking off the question mark on the end but try it with the question mark first
