Just a heads up for those of you who do not currently have an iPhone/Android - If you own a iPod Shuffle device that works just as well as an iPhone. You can DL the Instagram app for free (via wifi), set up an account also for free and load any picture you've taken from another device that you've uploaded to your computer onto iTunes then sync photos to your iPod, then iPod to Instagram.
Don't forget to hashtag #theory11
Hope that helps.
