Forced to restore my iPhone 5s? I'm so mad?

Today Apple asked me if i wanted to update my iPhone to 7.0.6 and iTunes forced me to restore my iPhone. I lost all of my photos and apps and EVERYTHING- it restored it from my old iPhone 4 layout and everything so all of my backups since i got my iPhone 5s are missing. I'm so mad! Is there any way to fix this? MAKE SURE YOU BACKUP YOUR IPHONE BEFORE GETTING THIS UPDATE OR YOU WILL LOSE EVERYTHING! THIS IS THE FIRST ERROR I'VE EVER RUN INTO WITH APPLE… I'm very disappointed.

Actually its your responsibility to back up the phone, you shouldn't have to be told that. If you backed up to icloud then all that will still be there, itunes also keeps multiple backups. The key thing being… You have to actually back it up.

Yeah, you can't restore your iPhone mistakenly from unknown backup or very old backup, or you will lose all your recent data on iPhone. BTW, i heard that iPhone data recovery software can recover iPhone data without backup. You can have try if you really need your data.
I can recommend you one called Tenorshare iPhone data recovery, you can search on the internet to get more options.
