Any iPhone users ever got the warning in the image below ? A friend of mine just posted the picture on her Fartbook page and I had a look on the interweb, but there isn't much to say what is actually causing it.
Aye, had this happen few times on my phone which is a Motorola. I was not expecting it the first time it happened. Most instances were due to my forgetting it lodged on the holder on dash when I was using it as a gps and left it unattended in the car during summer months. The poor thing was almost red hot when I came back and the message showing.
