If you are upgrade eligible and your account is in good standing, you will pay $199 for 8GB (black) and $299 for 16GB (black or white). Two-year contract required.
You have the option to purchase an early upgrade priced at $399 for 8GB (black) or $499 for 16GB (black or white). Two-year contract required.
