I've been searching for similar questions but have been coming up with a mixed bag. I want to restore my phone maybe from new but not sure. Its been kind of running sluggish recently (iPhone 4) even after a restart and closing all apps manually and latest software. I'm kind of concerned about doing a new restore. I've never done either (new or back up) and I'm mostly worried about my notes (has info for work) and work mail/contacts getting wiped. I'm just wondering if I do a new restore and then plug up to sync will I be ok with all my concerns (notes, mail, contacts, pics) after syncing back up? Thanks in advance for the help.
