IPhone ringer toggle is broken, any other way to turn ringer on/off?

The speakers very clearly work, and the phone's volume function, just the ringer on/off toggle and ringer volume buttons are non-op. Is there a way to turn my ringer on/off without the toggle and adjust the ringer volume without the buttons. I have an iPhone 4 and am running iOS 7.
If there's an app that'll handle it you'll get your 10 pts. For sure.

Find Assistive Touch in the Settings give options for the phone such as Turning it on and off and Silent and Speaker stuff.
