Is AccuFuel 1.1.1 a free update to previous owners of AccuFuel?

Yes. We recommend first synchronizing your iPhone/iPod touch with iTunes before performing the update. Please make sure that you do not delete the application. Deleting your application (if you read the small print of the pop-up window that appears) will not only delete your application, but also the associated data. Also, please do not turn off your iPhone or otherwise use it during the update. Some users have experienced problems by not allowing the update to finish completely before using their iPhone/iPod touch.

Additionally, if the update does not already show up in the App Store on your device, just search for "AccuFuel" in the App Store. Once you've found it, press the $0.99 button and then "Buy Now". It will prompt you for your account password. After you enter your password, a pop-up screen will appear to say that you've already purchased this application and you can then download it for free.
