Will downloading iOS 7 wipe my music?

The last update I got was iOS 6 from iOS 5 last year. I haven't updated my iphone since September of 2012. Will it affect my phone's memory?

Nope

As long as you have a back-up, I'm pretty sure it won't delete your music.
I just updated both my phone and my mom's.
Nothing was deleted for both of them, everything's still there all our apps/photos/music/etc.

I just updated, and everything is fine.
but backup. You never know with software updates.

  • Will updating my iPhone 4 (not 4s) to iOS 6 wipe out my whole phone? I read online when you update to iOS 6 its deletes eveything and I don't want it to will it? If it is I'm keeping it to iOS 5
  • Will downloading IOS 9 delete the storage that iOS 8 took up? I have a 16gb iPhone 6, and it come with iOS 8, and I only had 11.6 gb to work with as soon as I got the phone with all of the software installed. My question is: will downloading iOS 9 delete the iOS 8 data, thus freeing up more space after the download because iOS 8 took up more storage?
  • What's a free music downloading app for IPhone? Ok so I've been looking for good music to put on my IPhone. I've been using iTunes but I can't find any of the songs I'm looking for, it just says "sorry could not find song" so I was looking for an app maybe that I could type in a song and find it. Or a website.
  • IPhone apps for downloading free music? I want one that puts the music onto my iPod app that came with my phone. I already have music on there and so I want to add to it. My iPhones jailbroken too so I have the mewseek app but it stopped working. Do you know of any good apps where I can download music for free and put it in my iPod app?
