Since upgrading to 1.02, my iPhone has killed itself 3 times. When the phone is locked, it will get real warm and kill a fully charged battery in about 2-3 hours. When this goes unnoticed it will eventually kill itself. Otherwise, it just gets *real* warm and drains the battery faster than when using it. I thought the first time that it happened that it was a Mail issue, but now it seems it might be related to Safari activity. Has this happened to anyone else? I'm concerned that it can kill itself quicker than I can when using it.
