Version 04.32 of TinyUmbrella was just officially released a few minutes ago. The new version saves the SHSHs for iOS 4.3.2 for all our devices both on the computer and in Cydia. SHSH files are necessary to restore to any version of iOS 4 and if you don't have them iTunes will refuse to restore giving you error 3194. These files can be saved ONLY for current firmwares, so don't try to save for versions old because you can't.
You can download the new version of TinyUmbrella from here: Windows, Mac OS X
