If Engadget is to be believed firmware version 1.1.2 will be made available to download this friday (9th) http://www.engadget.com/2007/11/04/iphone-v1-1-2-breaks-jailbreak-coming-to-the-uk-on-friday/ Other than the tiff exploit patch I doubt there will be anything worth upgrading 1.1.1 for. For the security conscious a fix has been made available in installer anyway.. Anyone paranoid about the control click restore method being disabled in the next Itunes version may want to restore thursday. You can always jailbreak again on the weekend... Cheers.
