the reason it is getting hot it's because the phone is trying to connect to a network and there is no signal prob....also you might want to check and see if your wifi is on. I notice recently with mine, if the wifi is on and it is not getting to connect to the wireless router, the phone gets REALLY hot....

hey simran, maybe you should check and see if there is something shorting in the area of the sim card - maybe metal particle slipped in there some how....
