My iPhone was running out of space and was having heat problems, so I decided to restore it.
Whenever I delete music, it turns into "other". Since this morning, I have also been unable to backup, sync or restore my iPhone, and attempting to do so crashes both iTunes and the phone.
Any ideas how I can resolve this issue?
