This is the new goal that the Dev Team has set for iOS 4.3, which will appear in the near future. If you think that you can get rid of SHSHs to jailbreak, well you are wrong because the Dev Team will use them in the future. This time the Dev Team is planning to use SHSHs of iOS 4.2.1 to jailbreak iOS 4.3, so I recommend you save iOS 4.2.1 now if you haven't already! Apparently the Dev Team considers that the solution involving the use of SHSHs is better than what the Chronic Dev Team developed, or maybe they have nothing else.
In any case, saved SHSH for iOS 4.2.1 because you will need it in the coming months!
