Plugged my iPhone 3GS into my computer a while ago. Instead of the usual chirp, the screen went black. No matter what I do, any combination of keys I press, it's still dead. I even pulled the SIM. Still that black screen. Not the "LCD is on but displaying black" screen, the "this device has no power whatsoever" black screen. Strange thing is, it has been 20 minutes and the phone is still hot. Like real hot. Like warm your hands hot. I'm going to let it just sit for a while (hours) and then mess with it again. And if it is still dead, it's back to Apple. Was Jailbroken, if it matters, and I do have Apple Care Protection. Let's hope they don't know and it doesn't void my coverage plan.
