Not long after the release of the carrier subsidized iPhone 4S, with the most recent launch on rebranded regional carrier C-Spire a few weeks back, Apple has now started direct sales of the unlocked version of the 4S with the models priced at the prices seen above, reflecting an identical pricing structure to the iPad 2 Wi-Fi+3G models. Apple also takes great care to note that while these models are factory unlocked and can be used on any carrier’s GSM network, the phone cannot be activated on US CDMA networks.
