use mac to create ipsw file and pc to jailbreak.
is it posible to create the ipws file with a mac and use a pc to do the jailbreak.
i know, sounds weird but a friend has a iphone 3gs, she lives very far from me. the iphone is giving her a lot of trouble lately and wants to restore. i've been searching to do it on a pc but everytime i read something i get more confuesd. to many tools.
the thing is, i do the ipsw file in my mac and when i visit her we do the jailbreak and unlock in her pc, is this posible??
her iphone is 3.1.3 and we are goint to upgrade to a 4.0 is this posible???
thanks a lot.
