(adsbygoogle = window.adsbygoogle || []).push({}); So I'm seeing a bunch of jailbroken AND unlocked iPhone 4s on ebay. They sell for $200 over the price of a regular locked/non jailbroken iphone 4.

Where the heck are the jailbroken AND unlocked iphone 4s coming from?

They are coming from people like you and me, and people that are investing in iPhones, jailbreaking them and then selling them on eBay for more than what they bought them for.

You'll notice a lot people who sell em assume a jailbreak is worth more when it's completely free and easy to do. A little googling goes a long way but there are newbies who are too scared to jailbreak the device itself and don't have a clue how to do it. Thus resulting in the sales of these overpriced iDevices. Just my opinion

The general public, but Id go in with caution, not everyone can be trusted.
