How to remove Cydia from iPhone 5 if I can't connect my iPhone to my computer?

So I need to take my iPhone in to the Apple store because it isn't keeping the charge but I have Cydia installed and another problem I'm having is the my iPhone won't connect to my computer. There's always an error and I've tried connecting to 2 different computers. Is there a way to remove my jailbreak without restoring through iTunes?

The quickest method to uninstall Cydia would be to access it on your device with all features loaded completely, hit Manage, and then go to the 'Packages' option. You will be provided with a list that includes Cydia once you find an 'Edit' option on this page. Select 'Cydia', and tap the button that will have a red minus sign, the typical Apple signification of a deletion or removal.
