Received mine on day of launch and after setting it up, later tried to power it down because it wouldn't be needed for a while. Couldn't shut it down. (Yes, I know how to shut the iPhone down). Each time I powered it down, it popped up again with the Apple logo and performed a full reboot. Tried to shut it down immediately after, same result. Tried hard reset. No change. Ended up doing this for almost 2 days before it finally stayed off when I turned if off. That problem seems to have fixed itself.
Still having numerous other issues with the phone, and even tried a full restore to factory settings. Those other issues continue to persist, but the constant rebooting thankfully has not re-occurred.
Same here. just got the 4S and it restarts every 2 hours or so.
Here is the log file which I don't have a clue of what it means:

I have the same problem. My iPhone 4S 32gb was purchased yesterday. Happend 3 times so far today. My crash report looks exactly the same as Ighal's above.
My battery is also draining disturbingly fast even after I turned off "Setting Time Zone", which was reported by the Guardian (I think) to drain the battery due to a bug.
While I don't think anything "official" has yet come from Apple, other than a notation that they are collectively looking into some of the notable issues that have arisen regarding perhformance bugs, much of what I've seen in these and other forums seem to indicate some defects that are not user rectified by restoring or changing settings on the device, but rather must be swapped out with a replacment. While it is impossible to say whether or not yours falls into that category, I would suggest that if a replacement is in order for you, I think your options are limited. If you have no authorized dealers to which you can go and swap out the device, you'll more than likely have to contact Apple, file a complaint for a claim number, and then send the device in for replacement. If possible, you also might consider sending it back to your father, and letting him take it in to the dealer in Kuwait from which it was purchased, indicate what is wrong with it, swap it out if that is an option, or have it fixed under warranty if that is possible, and then send you the repaired or replaced phone. All of these considerations mean that you will be without the device throughout the process. Hopefully you will have other means of connected communication during that time.
I finally booked a Genius Bar appointment and took my affected iPhone 4S in: reboots 2-3 times a day (or more often), sometimes reboots to be back on, other times it requires me to do a reboot to bring it to the on state again. Annoying and NOT going away after 3 weeks of use.
If you actually go to Settings>General>About>Diagnostics & Usage>Diagnostics & Usage Data you will see a series of 'files' or entries. The ones with "...panic.plist" raised the alarm at the Genius Bar and they are directly associated with these reboots. It is apparently a kernel panic.
The Genius Bar suggested a new phone gets ordered but since none was in store, they offered to do a more drastic reset than the user can do at home in the hope that this might fix it in the mean time. Apparently a similar problem has affected the iPhone 4 and 3GS models in small numbers.
I left all hopeful, however, to my dismay I got 2 more reboots, one 8 hours after the above 'fix' and another an hour and a half later. The "...panic.plist" file name has as its starting name the date/time in yyyy-mm-dd-hhmmss format, so if you have this spontaneous rebooting problem, go look in Settings>General>About>Diagnostics & Usage>Diagnostics & Usage Data and see if you find entries with names such as "yyyy-mm-dd-hhmmss.panic.plist" and that the date/time matches what you saw as the reboot issue date/time. I bet you it does.
I'm now awaiting a phone call from the Apple store when the replacement phone is in the store for me to go and pickup.
Genius bar appointment was to get the problem diagnosed. Once diagnosed, they ordered a 'new' one for me. I got an email that it had arrived 2 days later and they hold it for 5 days and you can just go in to pick up without a wait or without an appointment. You just need to bring with you the paperwork they give you at the Genius bar appointment you started off with and a photo ID.
The 'new' phone comes in a crude container, so no flash colour printouts, etc. which is fine, and no charger or cable (they only take back your old phone and replace it with the 'new' phone, so no issue here either). Why do I keep saying 'new' phone ... well, because technically it may not be 100% new. Apparently, all items except the logic board are new, but the logic board may well be reused from another phone. Since the iPhone 4S has only been out 2+weeks, chances are that there has not been enough time for dud phones returned to have had their logic boards fixed, etc. to find their way into the replacement 'new' phones, so likely that my iPhone 4S is indeed 100% new throughout ... but in the end who knows. Ticked me off a bit but the manager's explanation was good enough and of course any other issues I can take it in again.
Note: the new phone has not had the previous issue again. I've been using it for 24 hours and no problems yet. Previously, I had shut-downs and auto reboots several times a day. Genius bar diagnosed it as a problem at their end since some apple apps (as well as other apps) were causing the kernel panics and shut downs. Read my comment from 2 Nov above re how to spot this particular problem from the settings menu etc. and diagnostics logs.
Brand new iPhone 4s (32Gb).
Happened to me first time couple of hours after activation:
Took it out of my pocket, pressed the HOME button, and got the Apple logo. Few seconds after, got to the home screen and everything worked fine there (no need for hard reset as other users experienced).
Happened to me twice since (all during "sleep")...
As other already said, "panic" records are logged (Diagnostics).
I really hope its not a faulty device, since it was bought overseas (UK)...
