(Get Instagram's classic logo back in your home screen)
iOS only...because I'm lazy.
1) Move the New Instagram to your "Crap" Folder.
2) Open the link below and then add that page to your homescreen.
3) Boom! Classic Instagram Logo is back! *
* You will keep seeing the new logo in your push notifications and stuff.
...lame, but nothing can be done...
(open from iOS Safari Only!)
