Hey all, A couple of times I have been on long 3G phone calls, I'd say 2-3hrs, and my phone would get hot and would not charge even though it is plugged in. I know that Apple has came out and said that if your phone detects high temperatures then the phone could possibly not charge. That makes sense. But my issue is that I am not doing anything other than being on a long phone call over 3G. I even lock the phone so the screen stays off no matter what to help with the heating problem. Is anyone else out there experiencing this while on a long 3G phone call? Also, are there any other tips to prevent your iPhone from overheating other than the general tips that Apple has given us? Thanks.
