Just give it away to some homeless person. Might be of some use to them. Never mind, it's an Apple, they might just eat it.
I'd just throw it away in a junk drawer or somewhere. Not like it's worth anything. 10 bucks if that.
have one in my car on a cheap data plan, using it for a GPS monitor. Its Great, if i lend my car to a family or friend i know where they are all the time. Just had to wire it up.
