OT: What on Earth is going on with my eBay iphone auction?!?

[Aaron O]

I'm selling an iPhone 4 on eBay, unlocked, 32gb, heavily used otter box with 7 months of Applecare Plus left and one replacement and the bidding hit $400 with 6 days to go. This makes absolutely zero sense to me and I'm concerned that there is a data theft potential that I am unaware of, or people who pay with bad credit cards and stick you. Why would my used iPhone sell for $400?!? I've noticed that nearly all bids are international...do these go higher over seas?

I tend to worry when things are too good to be true, especially with intl. bidding, and this seems too good to be true.
