A new version of TinyUmbrella was released to provide some new features for unlockers and jailbreakers. Released by NotCom the developer of TinyUmbrella the new updated version 5.10.12 includes the support for saving BBTicket for iPhone 4, iPhone 4s, and iPhone 4 CDMA.
Although till now most of us are not aware of the usage of this new feature in TinyUmbrella 5.10.12, but I believe that the saving the BBTickets for your iPhone will help in future for some kind of jailbreaking, downgrading or unlocking activities. I am very trustful to our jailbreakers that they will never cheat us and will always provide useful things in future too as before.
As instructed by NotCom if you have an unlocked iPhone or plan to unlock iPhone in future, you should use this new TinyUmbrella version and save your SHSH blobs. Also as mentioned by NotCom you have to ensure that you have checked the overwrite saved SHSH option while saving the SHSH blobs.
I have given below the TinyUmbrella download links:
