iOS 7 Mail Crashing Instantly
Good afternoon,
I updated my iPhone 4 to iOS 7 two days ago and Mail keeps crashing instantly when I launch the app. I tried to reset the phone a few times and tried to delete all the accounts as well. Mail even crashes on the "Welcome to Mail" page when there are no accounts. I am able to check my email sometimes but 95% of the time the app crashes instantly. I maded a back up prior to updating to iOS 7, can I use this back up to restore even though I was running iOS 6? Please advise thank you in advance.
iPhone 4, iOS 7
