I love Siri. I've had that app for like a year, it's always worked well for me
I don't understand why theyre pretending it's new for the iPhone 4S...for sales I guess, but Siri has been available as an app for a long ass time.
Maybe there's something I'm missing or an addition to its capabilities I don't know about, but it sounds like the same old app I've had for a while now.
