Updating Instagram app and it's been stuck saying "Waiting..."
I tried to update my Instagram app and it's been stuck saying "Waiting" for several days now. I've tried powering on and off the phone, I can't delete the app on the phone or when it's plugged into iTunes on my macbook. So I can't update or delete the app, I can still update all of my other apps so this one is just stuck! Any advice?
iPhone 4S, iOS 6.1.2
