The unlocked iPhone is slated to be released on Sept. 21 and the Apple Store has posted how much customers can expect to buy the phone for when it is out on store shelves. 

16GB will be for $649, 32GB for $749 and 64GB for $849. 

When the iPhone 4S was released, the unlocked version did not go out for sale until almost a full month about the carrier-subsidized versions. So the Apple is only improving. 

Preorders for the iPhone 5 is available starting Sept. 14 by carriers AT&T, Sprint and Verizon. Shipping dates vary depending on location of delivery. 

The phone will go on sale in nine countries -- the U.S., U.K, Canada, France, Germany, Australia, Japan, Hong Kong and Singapore -- on Sept. 21, according to The Huffington Post.  

With a two-year contract, the locked version will be priced at $199 for the 16GB model, $299 for 32GB and $399 for 64GB. Cricket, a phone carrier, announced this week that they will begin selling the iPhone 5 on Sept. 28 with no contract, for those who prefer a non-binding agreement. Their sale will go one exactly one week after Sprint, AT&T and Verizon customers will have access to the iPhone 5. 

AT&T will allow customers onto their unlimited data plan to stay with the carrier even if they pay a subsidized price for the iPhone 5. However, 9to5mac.com reported that Version is opting for a different plan. A rep from the company told the site that customers will only be able to keep their Verizon Wireless unlimited data plan if they pay full price for the new Apple gadget. The rep also said the following:

"If you are an existing customer and want to keep your Nationwide Usage Based plan, you can keep your plan, purchase the iPhone at the discounted price with a 2 yr customer agreement. Only customers who are new to Verizon Wireless will select from Share Everything Plans."

Sprint stated their own take for the carrier's customers. 

"iPhone 5 requires activation on one of the Sprint Everything Data plans starting at just $79.99 with Truly Unlimited data, text and calling to any mobile. No throttling, no metering and no overages, all while on the Sprint network. "
