Following the iPhone 3G’s discontinuation of the original iPhone’s iTunes-based service signup and activation, Apple has launched a new online tool that lets customers planning to purchase an iPhone 3G review their eligibility and pricing, select an AT&T rate plan, and inform their local Apple Store of when they would like to come in to purchase the device. As all of these steps were previously handled for iPhone 3G customers while in-store or through an in-line, on-site screening process, the tool is likely designed to help reduce the amount of time it takes customers to purchase and activate their phones. It will also likely help avoid confusion when/if there is an AT&T-related issue, giving the user a chance to sort whatever issues may arise with AT&T prior to coming in to the store.

The service appears to be available only for U.S.-based customers at this time.
