Apple finally started taking the orders for unlocked iPhone 4S in the US. Apple has been selling iPhones on contract so far and now you can buy an unlocked iPhone from Apple by ordering here. iPhone 4S 16GB costs $649, the 32GB version costs $749 and 64GB costs $849.
Verizon and Sprint users should keep away from these unlocked units as these phones are not compatible with the Verizon and Sprint CDMA networks. At the moment, users can only order and get the phone delivered at their place instead of choosing to pick from the Apple store. And for those wondering, yes these phones will work anywhere in the world with any GSM networks.
