I have it! Download the new version of tiny umbrella and it works! I had the old version and it said I was too late and all that stuff. I updated and it was successful! But I don't understand what exactly I am selecting in iTunes to update my iPad. I tried selecting the firmware you download from the link and iTunes says it is like invalid software.
Make sure in the new version of tinyumbrella, that you are selecting the right firmware to request the SHSH blob. When opening tinyumbrella, it defaults to 3.2.2 iOS. Make sure it is on 3.2.1. Let us know...
