iTunes been deleted, will I lose stuff?HELP
I can't download the new iOS 7.0.2 because I cannot back my phone up since downloading the new iTunes on my laptop, and I can't use iCloud either. When I try to go on iTunes it says it needs to be reinstalled, I'm scared to delete and reinstall though because I'm worried my library and pictures and entire phone content that I've been building for four years is going to disappear! HELP ME
iPhone 5, iOS 7.0.1
