Be realistic. Someone asking about the upgrade process that doesn't mention shsh blobs has no idea what you're talking about.
Kaitlin:
Dev-Team Blog Go to that link. At the end of the first post is a group of links for redsn0w. Choose the one for your computer. Run it. Choose Extras, SHSH blobs, Query.
That will tell you which blobs Cydia has stored for your device. These blobs are specific to your device and you cannot downgrade without them. Whatever list you have there is the options you have to downgrade. If none are found, you won't be able to downgrade. When you can tell us which you have available, we can help you better.
