I can't sign up for instagram

The instagram app came on my iphone 4 automatically so I didn't have to install it. Anyway I was signing up for an account by putting all my info and stuff and then I press "done" and it loads then it says "Your version of Instagram is out of date. Please upgrade your app in the App Store to sign up for an Instagram." Then whenever I go to the app store and click "update" for the instagram app, it says "This app requires iOS 5." I don't know if calling customer service will help. Is there any way I can update to iOS 5 on my own?
