Download Custom Firmware iOS 4.1 for iPhone 4 [Windows/Mac]

Update : The latest version of Redsn0w (Windows) can enable that tricky DFU mode on Windows! Macs can use the Pwnage tool to create the custom firmware itself…

Warning : This isn’t for the faint of heart. I did not post a detailed writeup cos’ DFU mode is kinda tricky on this one. If you know what this is and what it means, go ahead and try this. All others, please wait while other Windows users verify this.

    1. Please use tinyumbrella to kick it out of restore mode. As I mentioned, I haven't tested on Windows and DFU complications exist with Windows. sn0wbreeze may help (once they add iPhone 4 support).

  1. Hey Kiran, I would like to know which version is for official carriers? The one reading: "[Official iPhone carriers]", reads "Activated" in the description. Shouldn't it be the other way around?!
