Can somebody please explain to me (in simple terms) what Odin is, and how I use it for the Captivate? I have a vague idea, but I'm not quite clear on a few things, and don't know where to get it, and how to use it. If I understand correctly, it flashes my phone to factory fresh using ROMs. If I'm right, then I can use it to restore my phone(ATT apps and all) if I need to send it in for repair at AT&T. Am I right?
