Hello there, I have downloaded PwnageTool 3.01 Mac (from this side, menu on the left), and have downloaded (but not install) the iPhone2,1_3.1_7C144_Restore.ipsw. When I select this file from PwnageTool 3.01 it tells me wrong firmware. Where can I get the latest PwnageTool to be able to upgrade to 3.1? I have a 3GS, mac mini running Snow Leopard and iTunes 9. thanks.
