I am continuing to have issues JB'ing my iP4 on iOS 4.1. I had decided to delete and reinstall Greenpois0n after re-installing iOS 4.1. I have successfully deleted and reinstalled GP on my PC. I am now having an issue with the iOS 4.1 software now however. When I install it (I've used several sources, including the link at iPhonetechie.com here: http://www.iphonetechie.com/2010/10/how-to-update-your-iphone-4-without-upgrading-the-baseband-with-the-help-of-tinyumbrella/), I am getting several files with the extension .dmg, and no .ips files... I successfully updated to iOS 4.1 some weeks ago without issue (preserved my BB w/ TinyUmbrella). Now that I'm looking to restore again (to solve any potential issues since I'm still unable to Jailbreak with GP or Limera1n). Any idea why these files are DLing like this?
