Can you guys post what you did that made it work? I have a 2g iphone, 2g firmware (iPhone1,1_*), and I'm still getting that error. I've tried 3 different ipsw's, 1.1.4, 2.1, and 2.0.2, and Pwnage doesn't seem to recognize any of them. The phone is not activated, and has a t-mobile sim, so iTunes (8) doesn't interact with it (or rather it tells me my sim is incompatible). Any ideas? Do I need some special firmware? Can Pwnage not help me? Ziphone worked for me before (I've since restored, but to what I'm not sure), if I use that again can Pwnage then get me up to 2.0+ and Cydia? thanks!
