I've seen it on mine. Not to worry, it's Magical... ha ha ha. This phones a joke. I'm so glad I don't rely on it. It's just a cheap toy.
Got a tip for us?

iPhone 4 - Temperature Error Lock Up

It's strange that you would get that warning when your phone isn't hot. My iPhone 4 gets noticeably warm to the touch and I've never gotten it. If I were you, I would give AppleCare a call just to be safe.
This happened me today. The phone wasn't even remotely warm. I restarted the phone and it was back to normal. Really weird.
I've seen that error before just because it's been posted online, but I've never seen it myself... and I spend my summers in Florida.
If yours was reporting that in a 72 degree office it sounds like something is wrong. Maybe the sun was beating down on it through the window?

Same thing happened to me today as well for no apparent reason. My phone was not hot at all and was not even being used at the time. It was in my locker at the gym. 
I pressed the sleep wake button a few times and it disappeared. If it happens again, I am gonna go see a genius.

I too have watched as this warning has appeared on mine, when using it in my office at work. The ambient temp of the office is a steady 70 F. At first I was surprised, but now that I've reframed how I think about the iPhone 4, it's no longer a concern. Since mine displays nearly all the faults that Apple calls normal, I've lowered my perception to that of a cheap dumb phone. It's now my secondary phone anyway. In that capacity it no longer matters.
Actually I wanted to start a topic about this to see if anybody else had this problem.
To me it happened while the phone was in my pocket (not in direct sunlight). I missed a call because of it. After I pressed the the sleep and home button a few times it came back to life.
I'll test it in the next few days but if it's that sensitive to heat it's going back. I need a reliable phone. It kind of sucks because I otherwise like it.

Same situation as the OP. Phone cold and sitting on my bed unused for 30-45 min in room at 72 degrees, out of direct sunlight and no background apps running. I picked it up to make a call and got that warning. It went away after 5 min. I already have the yellow band which is still there after a week (fading a bit I think) and contemplating a trip to the genius for a replacement. My husband's iphone 4 has had no issues.
Happened to me today too, first day I have had it; had to spend $169 to upgrade my OS from the "ancient" Tiger so I could use the darn thing, then it sats outdoors in 75 degree weather for 15 minutes and I got this message. Needless to say I was
I can tell you honestly that in the past two days I have spent at least 5+ hours trying to get my iPhone 4 to work, and frankly if I didn't expect it to be AWESOME I would have already returned it. And not for nothing but when I have called Apple Tech Support, literally 5 times out of 6 the line went dead either while waiting on hold, or maddeningly, while speaking to a representative.
It's ridiculous and amazing the stupidity, expense and assorted other hoops we will jump through for a CELL PHONE.
But the screen sure is purty.

Just got the same warning on call receipt
I'm an english user of iPhone 4, got the same temperature warning with "notruf" on the slide but the rest of the warning in English. Phone was sitting idle then the alarm went off. Could not get into the phone for about a minute. It was NOT noticeably hot or even warm.
After a minute or so was able to get into the phone, and my Phone "Recents" tab showed a phone call coinciding with the overheat time. I checked with the caller, who had in fact called then.
I'm charged at 66%, hadn't used the phone in more than an hour, and nothing in my multitasking menu seems to be a likely culprit for causing actual overheating. 3G and WiFi both enabled, both with good signal strenth (5 bars, 3 arcs).
Apple says they're not getting reports on this. Their suggestion is to Restore as New Phone, and if it happens again they'll swap out the phone.

I had the identical thing happen. I am sitting in an air conditioned room, with the phone sitting idle on a table next to me. Got a call, went to answer it and got the temperature warning. Phone was not even warm to the touch. Not sure what the heck is going on. The battery was at 70% charge.
Even worse...
Room temperature: 67 degrees F.
iPhone battery at 38%
iphone is actually a bit cold, like room temperature aluminum on touch.
I have been unable to use, charge, synch my phone for the last 2 hours with the same message shown here:

Reboot the phone by holding home and power until it shuts off and comes back on again. If it does it again, restore it in DFU mode. If it still does it, take it back to Apple.
I believe that the temp sensor is in the battery circuit. Why? Because I fix iPhones and I once had a bad batch of batteries which gave this exact fault. Hence, if you have this recurrent problem, it is my assertion that a battery change will cure it.
When I called apple support and when I spoke to the Genius at the apple store, they both seemed to think that I had the phone plugged in and was charging it. Even though I made it clear it was sitting idle on a table. Your points about it being in the battery circuit jive with the questions they kept asking me - like it was in their support script.
Happened to me yesterday, but I accidentally left mine in my car yesterday when it was 98F. I have noticed my battery life declining though even before the incident. I'm not sure if the two go hand in hand.
iPhone 4 displayed temperature warning in air-conditioned office
My wife told me her iPhone 4 displayed a temperature warning in her office today which was in a cool air-conditioned office.
She had been in 100 degree heat for 5 minutes, took the subway, and then walked another 5 minutes in the heat, but the phone worked normally at the office for several hours after she got there. She used it only for checking email (no CPU-intensive things like games).
Then she then heard it ring inside a pouch, took it out and saw the temperature warning that locked up the phone for no obvious reason. The phone felt cool to the touch.

I had the same problem with my first 4G and my new one doesn't trip as much...
