There are millions of new 4S owners flirting with Siri all at once. The chick is tired. She needs rest!
If you commonly type the name iPhone as "Iphone" or "I-Phone"... or if you commonly refer to an iPod Touch as an "iTouch" or "I-Touch"...... Then you deserve whole bottle of habanero hot sauce poured into your eyes!
Im sure the next ios update will fix most of the issues people are having. I would expect a minor ios update as fast as a week or two from now. This is the reason the jailbreak guys arent releasing anything right now. Apple always does it with a new ios release. Beta test the ios, the release it to the public for the final beta test and see what people are complaining about, then release a update to fix the problems.
