Just because YOU have a problem with YOUR phone doesn't mean there's a problem with the OS. I have NEVER had a problem updating any of my iDevices since they came out, nor has anyone I know.
What is the purpose of your posting anyway? We're users here just like you, so your asking us what the OS folks ar working on is pointless since we would have no idea what Apple is doing.
I sort of have the same issue with one of our Iphone 4S. We bought it unlocked at an Apple Store. And it randomly shuts itself off every once in a while, not every day. To turn it back on you have to press home-lock buttons, as if you are resetting it. Only pressing the lock-on/off button does nothing. Has done this on ios 6.0 and 6.0.1 regardless of the battery %. Battery consumption is ok.
I've restored the phone several times and set up as new but it still does this. This particular phone has no 3rd party apps installed.
