Just a quick heads up: Notcom has updated TinyUmbrella to v4.30.05. This version now supports iOS 4.3.1 SHSH blobs for the relevant devices. Currently only the iPhone 4 (Verizon) does not have iOS 4.3.1 support as there is no iOS 4.3.1 available.

In case you 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:
