Apple has confirmed that the iPhone 4S will be available unlocked and contract-free starting in November, 2011.
According to the online Apple Store, 16GB models will be priced at $649, with 32GB at $749 and 64GB at $849.
However, in a somewhat confusing note on the page, Apple’s text says that “the unlocked iPhone 4 or iPhone 4S will not work with CDMA-based carriers such as Verizon Wireless or Sprint.” It’s unclear at this point whether the text was merely preserved from the iPhone 4 and carried forwards to the iPhone 4S, which operates as a dual-mode worldphone with the ability to switch between CDMA and GSM networks, or whether this is related to an actual software or hardware restriction with the new device.
