My launch day iPhone 4 is a bit choppy now and I was hoping if I restore it as a new phone it would become a little snappier like it used to be. However, I do not want to lose my notes in the Notes app, contacts in the Contacts app, and app data in a couple of my App Store apps. I'm using Windows 7 so I'm not sure how I can sync my notes to my computer if I needed to. Is what I want to do possible?
