If I update iOS, will it remove my jailbreak?

I have an iPhone 5 currently on iOS 6.1. I no longer want the jailbreak because it's causing too many problems, so if I update iOS to 6.1.4, will it remove the jailbreak? Will it remove my pictures, contacts, and other stuff as well?

I don't want to restore it because if I do then everything WILL be deleted and I don't feel like backing up everything, it would take too long haha.
