Last night TinyUmbrella 4.21.04 was released especially for those who have iOS 4.3 beta 2 installed in their terminals. The new version of TinyUmbrella allows us to save SHSH for this version of iOS because it is not known what bugs are discovered in it and SHSH could help us to do untethered jailbreak for example. You can save SHSH regardless of whether you have iOS 4.3 beta 2 installed in your terminals or not, so download TinyUmbrella from the official website, open it, connect your terminal to the PC, select it from the list on the left and press the Save SHSH button to save all your available SHSHs. You don't have to be jailbroken to save SHSHs!
TinyUmbrella 4.21.04 can be downloaded from here: Windows, Mac OS X, Linux.
UPDATED: Version 4.21.05 has been released, it seems to fix some bugs of previous versions. You can download it from here.
