For my iPhone, why is the "restore from backup" option not available in iTunes? I'm trying to back up and restore my iPhone using iTunes in order to attempt to get my supposedly successful carrier unlock from Chronic Unlocks to work. This is what Chronic Unlocks support recommended.

I have synced my iPhone to my computer in iTunes and confirmed that I have a recent backup.



I followed the instructions from Apple under "restore from a backup", but when i ctrl-click on my iPhone under "devices" in iTunes, "Restore from backup" is not visible in the contextual menu. It only shows:


Eject
Sync
Transfer purchases
Back up
Reset warnings




How can I restore my iPhone using this backup I have?


Mac OS 10.9.4
iTunes 10.7 (update: had to downgrade from iTunes 11 using these instructions in order to have iTunes recognize and back up my iPhone running iOS 5). 
iPhone 4, iOS 5.0.1
Apologies - to get the picture in, I need to 'answer' rather than comment...

I'm really not certain whether it's because you're on an old version, or that your machine can see no backup, but I get a totally different Backup section


I'm not sure I can contribute further, sorry - because I don't remember how iTunes 10 looked &amp; I'm on iOS 7 myself.

There is the possibility that Apple has essentially locked out iOS 5 now - but please don't take my word for it; I've seen posts about it but have no authoritative answer. 

(Please don't -1 me for this 'non-answer', folks ;-)
