With the release of a new firmware, Apple blocked the possibility of saving SHSHs for old versions of iOS. This will happen now as well because in a few days Apple will block the possibility of saving SHSH for iOS 4.3.1. If you haven't saved this SHSH yet, then I recommend you to download TinyUmbrella available here and save him while you still can. Notcom announced that a new version of TinyUmbrella compatible with iOS 4.3.2 will be available in the next few days, so we will be able to save SHSHs directly to the PC using that program. The saved SHSHs for iOS 4.3.1 I don't think have appeared in Cydia for most of you but they should be saved.
If you don't like TinyUmbrella, then you can install from Cydia the iSHSHit application that saves a SHSH directly in your terminal, SHSH that you can send by email and save on your computer.
