Temperature warning...

I would. I've heard of other cases of this. The reverse is not fun - when it overheats but no warning or shut off occurs.

I'm sitting in my car, with my Iphone4, and work BlackBerry, and I look down, and see that my Iphone4 has a termperature warning.... Does the BB have one?? no...

I stuck it in the shade of the car, and let it get some air, and them warning went away..

Is this thing damaged goods now??

Were you charging it at the time?

It makes sense for the warning to go off if the phone actually got hot. However, it didn't. As I mentioned before, it has gotten hotter to touch afterwards without a warning.... ?

I'm willing to bet it's a software glitch but you might ring up Applecare and see if they have any advice. They might document it or let you know if it is a "known issue."

One of the more well known issues slated for the 4.1 update is the proximity sensor that Apple said they are still investigating.

You might want to try other boards or do a google and you'll find some others reporting this as well. And did you do a search here? I've certainly read of others having this happen, so I think there are a few 4 phones out there where the temp sensor is off.

Had the iPhone 4 for about 3 weeks now and this morning was the first time I saw this temperature warning. The message popped up even though I haven't touched it for 30 minutes. It didn't feel hot at all. I had to force shutdown (by holding both menu button and standby though I wouldn't suggest doing this) and as soon as I turned it on it was ok again. I only use an Apple bumper as well for the casing.

Never seen this screen before (not even on the previous iPhone 3G and 3GS). Perhaps it is a one off situation.

I just got this warning !

wasn't even using my phone a text came in and BAM WARNING ! I powered down waited 3 minutes and powered back up so far so good.
Should I report it ! ?

It happened to me a couple of weeks ago as well. I was sitting on the couch watching TV, iPhone was sitting next to me sleeping. It was not charging. Suddenly, the screen lit up with the temperature warning. After a hard boot, everything was fine. I have not seen the issue since.

I've got that screen too a couple of days ago, and I found that it was cause by a background process because the battery level has dropped by 15% also while the phone was sleeping. Apparently it was caused by the Phone app (which indeed was the last app I used before putting the phone to sleep and seeing this temperature screen after some time), that was consuming too much CPU for unknown reason. I waited for the screen to disappear and killed the phone app (throught the multitask bar) and relaunched it, and all was fine than.

Seems to be a bug in iOS 4.x, at least 4.1, hope Apple will fix it in 4.2 🙂
