If I upgrade my iPhone to iOS 7.0.3 will all my music be wiped?

As it says above, If I upgrade my iPhone to iOS 7.0.3 will all my music be wiped?

No, it will not. The only thing an IOS upgrade does is fix what's wrong. All of your apps, music, messages, etc, will be safe

You must throw it in the pool and dry it in thoetaster then download ios 7

Not if you have your device backup up on iTunes. Just in case you want to jailbreak in the future I wouldn't recommend upgrading to iOS 7.0.3

No, your music, photos, movies, etc. Will not get erased. If you worry about that, you can sync your iPhone with iTunes before the upgrade.

  • When you erase an iphone of all of its content & settings, does this mean EVERYTHING is wiped? I wiped my old iphone because i got the new 6s. So my icloud is in use on my current phone, but i wanted to know, that since i wiped out my old on. Does that mean it would be safe to give it to a family member or close friend to use? Without having my personal info. On it?

  • Lost my iphone passcode, if I restore, does icloud get wiped too? I saved everything to icloud before hand and all my pictures are on my computer already so i'm just nervous about losing my contacts, bu those should be saved to icloud, i'm wondering if I end up having to restore it will my icloud get wiped too or will I be able to get to my contacts again?
  • I wiped my iPhone, can I get everything back by syncing with iTunes? I erased everything on my iPhone, can I get all my apps and photos and such back on it by just syncing with iTunes?
