Hello, I know that there is a dev version cracked bla bla but i dont talk about that. i mean more like: 3.0 is released then you buy it. can i just copy the file so i have 1 original and 1 to jailbreak ( when the jailbreak comes out Please Register or Log in to view images ). How does apple check if you payed for it or downloaded it? like a regristration system and would copying screw that up so i cant use it anymore? Its a bit unclear for me. sorry for my english mods: I DO NOT intend in this post to get more info about how to crack, where to download etc the 3.0 firmware!
