for the last couple weeks it seems that more and more often siri refuses to answer me. I don't understand why. Usually i just have my headphones on and i'm walking somewhere, so i don't want to pull my phone out, take my gloves off and all that to make a call. these aren't big requests. i'd say lately its around 80% of my requests, wifi or not, in the big city of chicago. has this been happening to anybody else? also, there are a few different versions of her refusal although the most common is "i'm really sorry about this but i can't take any requests right now. can you try again later?" do the other responses mean different things? how do i know if it is phone-side or server-side? all in all i wish siri were accessible as a regular app or had better settings so i could easily see my history, maybe clear some things, check my connection, etc. i've had a few times where siri stopped working completely until i rebooted or where it got stuck using my gps and wouldn't stop until i rebooted.
