iPhone 4 is one hot handset, catches fire

The iPhone 4 is definitely hot property at the moment, never mind the fact that it has signal strength issues. Who would have thought that it was hot enough to burst into flames as you can see here? This spanking new iPhone 4 caught fire when hooked up to a computer using the Apple USB cable which shipped with the device, and it could be a defective USB port error so a replacement is in store, if only AT&T has some stock available. Hopefully this is just an isolated case, since we haven’t heard anything like it since the iPhone 4 rolled out earlier last month.
