I tried this but I didn't see any new back up, only old two from my old iphone 3G. The sync process just wiped out everything I had in contacts, notes, messages photos, videos and everything in it up to date till 08/10/2014 to stupidly restore by latest version of iTune when sync it.
I have done exactly as "aami" said in his post dated on Aug 11, 2010 9:39 AM in his replay to dthomas86.
So, I had previously iphone 3G. I did only two back ups, the latest one was on 02/12/2012. Then on 2013 I bough an iphone 5. I used it without any connecting it to my PC (windows 7 64bit) and everything on my iphone 5 was fine until today I uninstall the old iTunes, then installed the latest version of 11.3.1.2 then plugged in my iphone 5 to my PC. A dialog box popped up and asked me to pick up one of two choices:
set a new iphone or restore from old one.
Since I totally forget about what I did more than two years a go, I chose to restore from old phone. Then I clicked Sync on my iphone, after that I found the disaster for my iphone. It wiped everything clean exactly as my iphone 3G was. Apps, photos, contacts was restored to iphone 3G to exactly what it was on 2012. No warning.. nothing.. I can't believe how stupid the developers and architectures of iTunes are. Yes guys I can judge them fairly enough because I'm myself is a developer with Microsoft Visual Studio .Net technologies. I didn't see this coming at all. I mean, if you want to format any drive you have, a pop up warning msg will till that all the contents will be deleted from that drive. I had a very valuable pictures for my wife and kids in different occasions. This made me really hate Apple products. I even won't consider this an honest error because it wasn't my fault in the first place. I read one of the wise guys in this thread saying all those complaining from the same error that caused by APPLE ITUNES that they should read the user manual. Oh God, give me a break. So, everybody's committed exactly the same mistake including me because we were equally stupid not to read the user manual. I will give my iphone 5 to my little daughter 9 years old and go for the real deal to buy Samsung Galaxy S5. I bought iphone 5 from Apple store for $849 last year. I can't even believe that this happen to me. I'm always careful when it comes to activities that will delete contents. But to allow a software to wipe everything from my iphone 5 without any warning message without my consent, I would held Apple full responsibility for this negligence. I will try and find the nearest Apple store from where I live and try to ask their support in this matter, although I'm sure that everything is lost forever, but I would like to give them last chance to prove they are still worthy to hold the title of Apple empire that Steve Jobs built it before he died.
