iPhone 4S Problems

I was an iPhone 4 owner, loved it, had no problems whatsoever.  So far, unfortunately, I am extremely disappointed in my iPhone 4S.  It's probably the ONLY Apple product that I am so far displeased with.  It makes me nervous to upgrade to the iPad 3 considering how much I love my iPad 2.  Anyways, enough of my complaining, on to the problems:

1.  All of my text messages converstations disappear and I cannot create new text messages.  It's basically as if the 'messages' app is just frozen, however it's not, because I can exit the app in a normal manner and everything else will work fine.  It goes back to normal after I hold the home and power button and reset it.

2.  Occassionally, if I swipe to the right to bring up the search iPhone screen and then swipe back left, I will be back at my home screen, but the keyboard will be stuck on the home screen.  When this happens, everything is frozen.  Again, resetting this fixes the problem, until it happens again...

3.  Siri.  Not one single day goes by that she "cannot take my request."  Come on, this is the main feature of the iPhone 4S...

4.  I get a phone call, I swipe to answer, but the touch screen doesn't respond.  So it keeps ringing and ringing and the swipe to answer function does not work and I miss the call.

Maybe I'm being unfair, maybe it's not the iPhone 4S, maybe it's iOS 5 not working correctly on the phones and maybe the problem exists on the iPhone 4 right now too, either way, not too thrilled..  Anybody else having similar issues?  Maybe I just have a defective phone.
