Update: The deal is back, from a different seller - head here to get it.
No one wants to drop $700-800 on an unlocked smartphone, but that might be your only option if you want the latest and greatest sans contract. In the case of the new Galaxy S4, eBay has been offering some compelling deals culminating in today's $599.99 offer. It's a heck of a deal!
The i9500 is the unlocked international variant of the 16GB GS4, meaning it will not work on LTE networks.
