I got my iPhone 3g last night, and I'm trying to jailbreak using Pwnage on my aluminum Macbook Pro. Unfortunately, after I get to the DFU mode, iTunes doesn't recognize the iPhone. I get an error 2100. I did a search and googled it and it seems some people are having the same issue but I haven't found a resolution yet. I think it has something to do with the new MBPs. Anyone have any suggestions? Thanks.
