I would love one of those codes if only I knew how they worked and how to work them - and THANK YOU!
Open the App Store app, go to the Featured and scroll to the bottom. Click Redeem and enter the code.
(Can also be done through iTunes on a computer.)
...the codes that get PM'd are for members that contribute to the site. If you only have one post and you are here for a code only you will need to watch the thread for when I post more and try and get one of those.
