Finally, TinyUmbrella has been updated to include support for saving your SHSH Blobs for iOS 4.3.2. There is a slight bug with Cydia’s servers so right now the only way to save your blobs for 4.3.2 is to get them straight from Apple. To do this you need to go to the Advanced options and there should be an option to get them from Cydia, just uncheck that box and you should be able to save them. This new version of TinyUmbrella has a new feature to visit their blog when updates come out.
