Only the reseller customers service are answering. :lol: For $330 an ITB camera I think they can do that more easy, because who knows, in the future you will order a new one.
If there is some 2.2 firmware, someday it will be uploaded on their site. Until now it is not so important because the camera is working well with no major bugs and if the owner didn't saw any improvements I think are not major just the usual korean tiny improvement like how is blinking the LED.
Will be nice if we discover a way to extract the firmware from these cameras.
enjoy,
