How content is restored to a new device after choosing start as new iPhone
I got a new 3GS that is built with iOS5.
The thing is my former 3GS had the iOS6 and hence my recent iCloud backups were done with iOS6.
When tried to choose "Restore from iCloud backup" I could only see very old backups (I assume latest iCloud backup with the iOS5). the apple support (at the Genius Bar) advised me to later upgrade to iOS6 and restore from iCloud; and right there he chose "start as a new iPhone".
Now I upgraded to iOS6, signed in on with my appleID under Settings>iCloud but can't find how to manually restore from iCloud and get to my latest backup (on the phone I see only manuall backup, no manual restore - I can't see anything to do so on iTunes neither)
iPhone 3GS, iOS 6.0.1
