my iphone is being buggy (installer.app) not working. I want to do a complete restore to factory settings and re-unlock it. When i go to itunes and hit "restore" it says it will restore the system back to factory setting AND automatically update it to the latest version (1.1.3) 
any way to restore while KEEPING my 1.1.1 firmware.
