so, today marks the day that my 4th iphone 3g bit the dust. first two were cracks in the casing. i smashed the screen of the third one, and i don't know what exactly happen this time. i was outside tanning, the phone was in the shade, and my mp3s started to sound funny. so i look at it, everything seemed ok, so tried to look at my timer. i couldn't navigate anywhere. so i took it inside and looked at it again. the startup apple was on the screen. it's been like that for 5 hours now... hard reset shuts it down, but the same frozen start up problem occures when i turn it back on. did that little amount of heat shut it down for good? if that's true, it's unacceptable. itunes won't recognize it, so i have a genius appointment tomorrow.
