TinyTSS - local server used to playback saved SHSH files during an iTunes restore.

It even works with non-jailbroken devices.

Umbrella - used to save the SHSH file of your iDevice to make it possible to later downgrade or restore the firmware.(Windows users need the 32-bit version of Java, regardless of OS architecture). It requires Java and iTunes to be installed. TinyUmbrella is a combination of two earlier tools, both of which were written by semaphore. (previously TinyTSS and The Firmware Umbrella) Ive installed TinyUmbrella 9.3.4 on several PCs, with different windows versions, and on all of them the installation seems to work, and the program starts, but it seems to just load some libraries during a splash screen and then nothing happens.
