After updating my iPhone Firmware from version 2.2.1 to version 3.0, I got big problems with the battery life and when I plugged in the charger the iphone became really hot and I thought it will melt away.
I was looking on google and found that I was not the only one to have this behavior since updating to OS 3.0. The problem for everyone seemed to be the same:
The problem is the new (or changed) “Push” Mail setting. After switching this service off, restarting the iphone the problem was fixed. I hope this might be useful to someone having the same problem, drop a line if this fix worked for you as well.
i hope this is the solution
i hadn’t heard of this yet, that is crazy, i would be very upset if my phone exploded because of this.
