The pre-orders for iPhone 4S are sold out for Apple and all the carriers, which means that there will be a few weeks of delay before an order placed online will be delivered to the customer, leaving behind the only option of going to the local store to get it.

The iPhone 4S has significant hardware upgrades, though it looks identical to the iPhone 4. It is equipped with an A5 chip, iOS 5, Siri Voice assistant and an 8-megapixel camera along with many features. It is available with a new 2-year contract for $199, $299 and $399 for the 16GB, 32GB and 64GB models of the phone, respectively. The phone is available on AT&T, Sprint and Verizon Wireless.
