[Q]

If i have a unlocked s4 can i flash any rom on it
you must have an UNLOCKED BOOTLOADER. so if you have AT&T not at the moment; other carriers too. which carrier did you purchase it through?
There is rooting, SIM/network unlocking, BOOTLOADER unlocking; not the same thing.

You have to wait until a bootloader unlock is released for the AT&T variant. There isn't one just yet.

Factory unlocked question

I just purchased a factory unlocked note 3, about to unpack it but was wondering if I can flash kernels on this phone being as its not a vzw locked bootloader. If so, where do I go to find a forum for that phone?

Your bootloader is locked. No kernels. Safestrap and TouchWiz based ROMs only.
Is there a way to unlock bootloader? Like on sprint, t-mobile phones?
