Download TinyUmbrella v5.00.02 for Windows and Mac OS X – One popular tool among jailbreakers is TinyUmbrella (Firmware Umbrella) created by NotCom. The first tool I know ever made to save and make backup of iOS SHSH Blobs easily. However one most favorite thing I love about TinyUmbrella is that a user can save iOS SHSH Blobs without even jailbreaking their iDevice, unlike Cydia which also automatically saves a users SHSH blob onto their TSS server -obviously requires jailreaking-.
TinyUmbrella v5.00.02 has been live to save SHSH Blobs even on iDevices iOS 5 beta 1 and iOS beta 2, yet it now also has full support to 5.0b2 SHSH file of iOS5 b2 on iPhone 4 CDMA.
If any of you are having any issues saving SHSH, simply head to [Advanced] >> Uncheck “Request SHSH from Cydia” >> [Apply Changes] >> then click [Save SHSH].
