Evening all, Hope you can help, first time I have noticed it. Tonight I came to pick up my phone to make a call it was on the table in a room 21C and tried to unlock it and it said "high temperature" with a yellow triangle with exclamation mark. My phone was cold to touch so I dont know why this has happened. The phone is about 8 weeks old and jail broken. Is it faulty has any one else had this?
