Will I still be able to update to KitKat?

I don't use the S3 anymore since I upgraded to the S5 but I would still like to be able to update the S3 and keep it as a backup. Since it's not on the AT&T network anymore and works only on wifi, will I still be able to update?

Sent from my Holy crap this is awesome S5 :-D

You should be able to. I don't see any reason why not.
