iOS 4.3.1 (8G4) bug? "Flash is Disabled"

I bet you thought I meant Adobe Flash, huh? Well that a whole other discussion.

I think I found a bug in the firmware, that involved the camera flash. Overall, I really don't think it is significant... more interesting.

Repeatable steps to make the iPhone think that the phone is overheated:

1. Start camera
2. Change to front facing camera by tapping the flip button (top right corner)
3. Take a photo or two of your beautiful mug!
4. Go to photo gallery to look at your beautiful mug
5. Tap the Done button
6. Tap the flip button to go back to the main (back) camera
7. You should now see a warning on the flash control
If you try to take a photo with flash, this warning dialog will appear:
"Flash is Disabled... The iPhone needs to cool down before you can use the flash."
8. Press the Home button
9. tap the camera... problem solved. The flash is now enabled.

This was tested while the phone was at a ambient temperature of 24 degrees Celsius.

Curious to determine if this is just my phone or others.
