Yes. If you restore your phone you will lose your jailbreak and all of the jailbreak data. It will put your phone back to the way it was the day you got it.
The shatter exploit that you are referring to is for a future jailbreak that isnt out yet. Shatter will jailbreak the device for life, but right now restoring a phone puts it back to factory settings.
