Apple has finally caught up with the huge demand for the iPhone 4S. For the first time since its launch way back in October, all models of the iPhone 4S are now shown as in stock.
No matter which model you go for, 16GB, 32GB or 64GB or which carrier you choose from AT&T, Verizon or Sprint, they are all in stock. Even the unlocked and contract free models too.
