Hello! I have a problem with downloading an .ipsw file for some weird reasons. Been downloading that same bundle for so many times from different websites. I have a Mac and a version of 1.1.4 iPhone and am waiting to have the awareness of the steps to upgrade it to 2.1 and be able to hack it with PwnageTool first, but then... the .ipsw file won't even show up in the right format. Instead, it's shown as a regular folder with some files in it and I tried to add the ".ipsw" extension in the end to that folder and tried using PwnageTool, yet it was notified as invalid bundle. So, what can I do to be able to have the actual .ipsw file without my weird computer converting it into a folder? Thanks.
