Where can i buy a cheap unlocked iPhone without a contract?

Where can I buy a (cheap!) unlocked iPhone without a contract? I know you can buy them from the apple store, but $749 is way more than I want to pay.

I basically want to use the phone as an iPod (like with Wi-Fi and stuff), but also be able to use it with a contract someday.

I know someone who uses their old iPhone like that- so can I buy one off ebay or something?

Just get an iPod touch if you don't need phone service.

Yea I think you should buy from eBay. I just bought my phone from eBay too. IPhone 5, unlocked and it's pretty new. I bought it for $525!
