UPDATE #1: TinyUmbrella v4.21.05 is now available to download. Download links below…

4.21.05 available. Sorry for the updates. There was a nasty bug in the iPad SHSH part of the code. Thanks everyone for your patience!

Its been weeks since we last heard from Notcom, the developer behind TinyUmbrella, a tool that helps save iPhone, iPod Touch, iPad and Apple TV SHSH blobs regardless of whether your iDevice is jailbroken. Today Notcom announced in a tweet that TinyUmbrella has been updated to v4.21.04 to support 4.3b2 beta SHSH’s.

For those who don’t know what saving your SHSH Blobs actually does, it basically allows you to downgrade your firmware to a lower version. This is important if you accidentally update to a iOS/firmware version that cannot be jailbroken, as Apple prevents this otherwise.

Follow our step-by-step guides below to save your iPhone, iPod Touch, iPad and Apple TV SHSH blobs using TinyUmbrella:
