I've got a iphone 4s whith a gevey ultra-s but i don't have the white reset sim card.
Can i update it or will I need to use the reset sim card afterwards?
 
I doubt you can update. SIM interposers generally rely on you to be jailbroken and on the fact that you are using a specific firmware. Update and that can throw that all into disarray. It will also lead to purchasing a new Gevey (if they are still making them) for the version of firmware you update to.
