Are you restoring from a backup made when the iPhone 3GS was on the previous firmware or on iOS5?

And, can we've more info about the iPhone? Is it Jailbreak? Has it been Jailbreak before iOS5 was installed? etc

Hi , there are no backups made with the phone so a fresh copy of ios5 was used to restore. Never been JB
