My friend and I received our iphone 4s's today and i finally got mine activated on crappy AT&T after hours of trying. Long story short, Siri seems to be completely useless and i wanted to see if others are also experiencing problems. Asking siri extremely simple things such as "Text Pat" do not work reliably. It will either screw it up completely giving "ex Pat" as it's response, or it will just say sorry i didn't understand you. Neither of us have any type of accent or speech impediment. We are both testing in a quiet room with little to no background noise. The reason i'm so confused is i've seen plenty of videos of this working far better in very noisy environments. Could this perhaps be an issue with apple server load? It would be great to hear other's experiences so far, I didn't expect Siri to be amazing but i did expect to be able to dictate extremely basic text messages which it is failing at completely, we are both extremely disappointed.
