I got my iPhone 4S as soon as it was released! I thought Siri would be just a show off feature, but I find myself using it ALL the time (sending texts, calling people, setting up meetings, playing music). I use it in the car a lot too, however I have found that when driving shouting at Siri cause he keeps getting things wrong, I bought a Jawbone Bluetooth headset thinking it would help ... not so much. Its down to my scottish accent, I've found myself asking it repeatedly something and not coming up trumps, however as soon as I put on a dodgy American accent .... works like a dream!! And I'm not the only one to find this!! http://www.bbc.co.uk/news/uk-scotland-15475989 Just thought I would share this!!
