when i press shift and left click i cant find the file. it will not see it in the folder where i saved it….any ideas?

tgouch July 24, 2011, 4:54 am

In order for the file to show up, you must first change it from a “zip” file to a “ipsw” file by replacing the .zip at the end of the file name to .ipsw and then it will show up.

how do i do that?

Snewt September 2, 2011, 9:42 pm

Very easy.

Just right-click on the “[…]” file, when’s it’s highlighted, simply remove the “.zip” suffix and replace/rename with “.ipsw” suffix.

Go to the web site and the article will explain what you need to do and how to go about changing your host files on your computer to trick iTunes into thinking it is communicating with apple but in reality it will be communicating with the cydia host. When you add the host source you must do it in safe mode for it to be saved. The article will also explain how this is done on a Mac.
