I just downloaded the Phocus Apps on my iphone but it lacks sufficient information to get me going. There isnt much info on the web/ H website on this and i read from other forum that the cam has to be tethered to the Desktop in the first place... Quite defeat the purpose... but i am sure the R&D team at Hasselblad has thought of this...
