ITunes should have backed everything up before it updated the iOS, if you wipe your phone and restore it then you "should" get the option to put the last backup that iTunes did back on your phone.

Unless you have previously backed up your iPhone to your computer or iCloud, then this is not possible. Sorry.

Just go to itunes, under your iPhone, click restore, then restore from previous backup. If you do not already have a backup, this will not work.

Did you back up with iTunes or I cloud? Then it should be simple to restore. Other people have said how do read theirs

  • May I delete everything on my iphone 4s once everything had been transfer to icloud? I have been a iphone user for almost three years and I'm going to trade in my 4s to get the iphone 5. Right now, I'm starting to figure out icloud work and it's a little bit confusing. So I want to know if it's okay if I can delete everything once my contacts, photos, and other stuff had been transfer? Because I do not want to lose my stuff and never get it back!
  • Is there a way I can get everything back on my Iphone? I have a iPod and a iPhone. I have had my iPod for a while and I just got my iPhone. I wanted to take all my music on my iPod and insert it to my iPhone. I was on my computer on iTunes trying to find how. I thought I found the right thing so I clicked restore iPod when my iPhone was plugged in my computer. Then I lost everything and I'm very upset. Also, my iPhone was acting like I just got it. It basically acts like an iPod. Is there a way I can get everything back?
  • If i restore my iphone via ITunes, everything will be put back on it from back up? I want to restore my iphone due to some problems i'm having but i wanna make sure i won't be losing anything. I backed it up to itunes, so where do i go from here? Do i do a factory reset and when its done, will it give me the option to use backup to put everything on my phone? I'm having a hard time understanding this and i don't wanna lose anything
  • If I restore everything to iCloud on my iphone, can I restore everything and get it all back? I have too many things on my iphone right now, and I was wondering if I can restore it and get everything back from ICloud
