Will updating to iOS 7 delete everything if I don't backup my storage to iCloud?

I have about 4.8GB left of storage in my iPhone 5 left but iCloud is acting up and it's saying there's no space to back everything up. What should I do? Should I still update to iOS7? It's stressing me out and I don't wanna risk anything being deleted.

I'm like 99.99% sure it won't.

Updating to iOS 7 won't delete any of your app or other stuffs.

  • Will updating my iPhone 3GS delete everything on it I have an iPhone 3GS and I want to update it to the latest iOS so I can download the newer apps. When I try to download on it says it will delete all of my apps and media on my iPhone. Some people say it will restore it back after the update but why doesn't it say it anywhere on the message that pops up? Anyway I'm one click away from updating… Will it delete all my stuff?
